NOTE:  [e-mail] is the maintainer of the
libraries as of PL26.

Changes are listed in *reverse* order, most recent changes being
first.

PATCHLEVEL38::

symlink.c:
    Set errno properly for readlink() on a non-link (EINVAL not EACCES).
lattice/setjmp.s: ++pvt1-117
    Add sigsetjmp() and siglongjmp() for lattice.
compiler.h: ++pvt1-117
    Make LCC do the right thing in limits.h.
termios.h, tcattr.c:
    Add VLNEXT and VWERASE control chars.
types.h: [e-mail]
    Add fd_set type and related macros.
falcon.h: [e-mail]
    Change return types of VsetMask() and Dsp_Reserve() from
    void to short.
_mulsi3.s, _umulsi3.s: ++schwab
    .lmul and .ulmul aren't equivalent.
read.c, write.c: ++schwab
    Reduce drag.  Also alias read to _read and write to _write
    when __GNUC__ && !__MSHORT__.
popen.c: ++schwab
    Reduce drag.  Also simplify code by using waitpid().
open.c: ++schwab
    Pass as many flags as possible through to MiNT, and let it decide
    what to do with them.  Only fall back on emulation if we can't pa a
    given flag.
ioctl.c, stat.c: ++schwab
    Reduce drag.
rename.c: ++schwab
    Try to preserve the old file under the new name as long as possible,
    in case an error occurs. Unfortunately we cannot determine exactly
    why Frename() failed, so this is not perfect (bug?).  Also, reduce
    library drag.
alarm.c: ++schwab
    Use Talarm() instead of alarm() to reduce drag.  Also
    fix a bug in the code for old versions of MiNT. [I messed with
    this a lot to get some more error checking and also added some
    comments. -entropy]
wait.h: [e-mail]
    Make the wait prototype indirection more robust.  Also fix the
    definition of WIFSIGNALED().
wait3.c:
    Remove bogus usage of non-existent rusage value added in PL37.
falcon.h: ++pvt1-117
    Inline traps for Lattice.
wcmb.c: ++pvt1-117
    Use _wnull from wnull.c instead of a local variable.
wcscat.c, wcscmp.c, wcscpy.c, wcslen.c, wnull.c: ++pvt1-117
    NEW files for ISO wide char support.
stdlib.h: [e-mail]
    Add prototypes for new ISO widechar functions.

PATCHLEVEL37::

bzero.cpp, mincl:
    Break bzero and memset into separate .o's (reduce drag).
gethostn.c: [e-mail], ++entropy
    Look in /etc/hostname instead of /local/hostname, and look in the
    file before the environment.
lattice/mc3.prj, lattice/mcnb3.prj, lattice/mcr3.prj,
lattice/mcrnb3.prj: ++pvt1-117
    Remove long mul/div with 030 code.
string.h, strcmp.c: ++pvt1-117
    Allow use of builtin string functions.
lattice/bcopy.s, lattice/crt0.s, lattice/inc.i, lattice/linea.s,
lattice/setjmp.s, lattice/vfork.s: ++pvt1-117
    If we're lucky, they might decide to keep us as pets.
file.h:
    Add FREAD and FWRITE macros for TIOCFLUSH flushing modes (not yet
    implemented in MiNT).
unistd.h:
    Add tcgetpgrp() and tcsetpgrp() protos.
ioctl.h:
    Changes to account for definitions in common with termios.h,
    also add _RTSCTS flag definition.
termios.h, cfspeed.c, tcattr.c, tcbreak.c, tcdrain.c,
tcflow.c, tcflush.c, tcpgrp.c:
    NEW files, partially implementing the POSIX termios functions.
    (UNTESTED).
wait.h:
    Add WSTOPSIG() macro (POSIX).
utime.c:
    Add a kludge so that we pretend the utime() worked for directories.
mkdir.c, stat.h:
    Mode argument is now mode_t instead of unsigned (POSIX).
mkfifo.c, stat.h:
    NEW file providing a fake mkfifo(), and a prototype for it.
mknod.c:
    Provide at least a little functionality in mknod().
resource.h, getrusag.c, wait3.c, wait.c:
    Add BSD-compatible struct rusage members with 0 values for
    minimal compatibility.
    Use Pwaitpid() instead of Pwait3() for wait() and wait3()
    (as requested in MiNT's dosmem.c).
errno.h:
    Added EOPNOTSUPP as (temporary) alias for EINVAL.
    Added ECHILD as alias for ENOENT (POSIX).
lattice/*.prj: ++pvt1-117
    NEW files:  48 new project files for Lattice.  Yow.
doprnt.c, fprintf.c, printf.c, sprintf.c,
vfprintf.c, vfprintf.c, lib.h: ++schwab
    Change the interface of _doprnt to also pass a putchar function
    similar to _scanf.  This allows use of sprintf in a program which
    doesn't use stdio and it simplifies the implementation of sprintf a
    bit.
fscanf.c, scanf.c, sscanf.c, lib.h: ++schwab
    The implementation of sscanf had a bug: the ungetc function would
    write into the scanned string passed to sscanf.  This is a Bad Thing,
    since the string could be in readonly memory.  Also changed the
    interface a bit so that there is less need for casts.  Strictly
    speaking, the old way of casting the function pointers can result in
    undefined behaviour.
getdtabl.c:
    Use _SC_OPEN_MAX instead of magic number 2.
lseek.c: [e-mail]
    Make lseek() and tell() always return -1 on errors.  Make lseek()
    work better with unseekable devices.  Don't modify errno
    when no error has occurred.  General cleanup.
lattice/osbind.s, lattice/lcsnb.prj, lattice/lcnb.prj: ++pvt1-117
    DELETED files.
nlist.c, select.c, sync.c, truncate.c: ++pvt1-117
    Add some typecasts to keep Lattice happy.
mintbind.h: [e-mail]
    Add some casts in the Lattice C inlines.
frexp.cpp: [e-mail]
    Bug fix: add a missing @.
read.c:
    Add the beginnings of some code to make read() POSIX compliant.
    It turns out that this will require kernel changes so this
    code is currently inactive.
lockf.c:
    Fix so flock() and lockf() block when appropriate.
dirent.c:
    Bug fix: rewinddir() wasn't resetting the directory offset to 0.
crtinit.c, ctime.c, doprnt.c, findfile.c, getpass.c,
localtim.c, strftime.c, strncat.c, unx2dos.c: [e-mail]
    Removed some dead assignments and increments.
stdlib.h:
    Added NULL (POSIX).
dup.c:
    Clear the close-on-exec flag of the duped handle for both dup()
    and dup2().
open.c:
    For O_TRUNC mode, try to use FTRUNCATE.  Also, clear the
    close-on-exec bit of the opened file.

PATCHLEVEL36::

mincl:
    Added target for nlist.o.
mincl, sozobon/makefile, lattice/mincl.lcc, purec/mintlib.prj: ++entropy
    Added targets for truncate.o, wcmb.o, printf.o, vfprintf.o,
    vprintf.o.
truncate.c, types.h: ++schwab
    NEW file, implementation of truncate()/ftruncate().  Protos in
    types.h.
getwd.c: ++schwab
    Make getwd() return an error message in the buffer on failure.
_addsubs.cpp: ++nox
    Correct an inverted branch.
open.c: [e-mail], ++entropy
    Fix so that when we use Fcreate() we then Fclose() and Fopen() the
    file, so we get sharing modes correct.
utime.c: ++schwab
    utime(NULL) uses time() to convert the current time to Unix format
    and immediately converts it back to GEMDOS format. Instead it should
    use the GEMDOS format directly.
    stime() must be changed because Tset{date,time} can now return a
    real error number. This depends on Tset{date,time} returning -1 if
    args are bad, which is true for all TOS versions, i think.
ttyname.c: ++schwab
    ttyname() should not return names starting with "u:" when _rootdir is
    'U', to be consistent with rest of library. find_ino now gets the
    dir name in gemdos format and it calls dos2unx on it.  ttyname.c
    unnecessarily depends on dirent.c, we know that Dreaddir works.  We
    can also avoid the hairy fstat(), since we know that Fcntl(FSTAT)
    works.
signal.c: ++schwab
    Pass through additional signal handler parameters via _trampoline().
rename.c: [e-mail]
    Eliminate a useless strcmp().
main.c: ++schwab
    When converting a path variable from the environment, we can conserve
    memory by using the fact that _path_unx2dos enlarges the path by at
    most two times the number of elements. On the other hand, if there is
    no PCONVERT env var, the provided space was too small.
isatty.c: ++schwab
    Removes the dependency of isatty() on ttyname().
spawn.c: ++schwab
    Cleaned up the script emulation code, and changed it in that only
    files starting with "#!" are interpretable (as Unix does).  The
    first 1024 bytes of the file are examined when looking for
    interpreter and arguments.  A small bug is also corrected: errno
    should never be changed when there is no error.
falcon.h: [e-mail]
    Add two omitted backslashes to fix new trap definitions.
chmod.c: [e-mail]
    chmod() unnecessarily calls stat() to check if the file is a
    directory; this information is already available through Fattrib().
nlist.c, nlist.h: [e-mail]
    NEW files nlist.c, nlist.h.  A version of nlist() for mntlib/toslib.
    Works OK with my binary config program but your milage may vary.
wcmb.c, stdlib.h: [e-mail]
    NEW file wcmb.c for ANSI wide char functions.
waitpid.c: [e-mail]
    Add a forgotten patch for non-GCC compilers.
ctype.h: [e-mail]
    The toint() macro in ctype.h was translating hex digits wrong.
--begin jrb changes--
math-68881.h: ++jrb
    -- Put extern "C" around file when __cplusplus
    -- Make hypot use internal version of sqrt (because signature
       clash in libg++:xfix )
    -- Define internal version (_sqrt) of sqrt.
osbind.h: [e-mail]
    Changed addw #n,sp to lea n(s),sp which is 4 cycles shorter.
fprintf.c: ++jrb
    Break out vfprintf, printf and vprintf into their own .o's. That
    way the user can replace any of them.
printf.c, vfprintf.c, vprintf.c:: ++jrb
    NEW files.
mincl: ++jrb
    Add targets for above.
gnulib2.c: Steven Ourada ([e-mail])
    #define WORD_BIG_ENDIAN for long long.
--end jrb changes--

PATCHLEVEL35::

unx2dos.c: ++schwab
    _unx2dos("/dev/.") -> ".:" -> file not found.  This patch isn't
    optimal, because it only works for the first 26 drives, but better
    than before. (Who has more than 26 drives anyway? :-)
wait.c, waitpid.c, wait.h: [e-mail]
    Accept both POSIX and BSD style parameters.  [I'm not certain these
    patches really leave us with a POSIX-compliant wait*() suite, but
    I'll leave it be for now -entropy]
Makefile: ++Bjarne_Pohlers
    Fix 020 targets to use 'make install020', and fix all targets to
    do 'make clean' only when necessary.
doprnt.c, scanf.c: [e-mail]
    Add support for printing/scanning long longs.
div.c: ++pvt1-117
    Add div functions for compilers other than GCC.
bsearch.c: ++dsb
    Fix bug reported by Thorsten Roskowetz: the order arguments to
    bsearch()'s comparison function was reversed.
sozobon/makefile, sozobon/readme: ++dsb
    Updated to reflect recent changes in the library.
thread.c: ++dsb
    Fix a strange declaration (extern static?!?).
sozobon/linea.s, sozobon/makefile: [e-mail]
    Fix some HSC linker problems by punting alglobal.o.
ioctl.h: [e-mail] (Jan-Hinrich Fessel)
    Make it possible to include both ioctl.h and filesys.h.
pgrp.c: ++schwab
    Correctly check the MiNT version in _bsd_getpgrp().
clock.c, doprnt.c, main.c, thread.c, uname.c: ++pvt1-117
    Changes to keep Lattice C from generating annoying warnings, and
    other miscellaneous cleanups. [Once again I've modified these
    patches in various ways, so if something's broken it's my fault
    -entropy].
math.h, process.h, support.h, unistd.h, exec.c, execp.c, findfile.c,
scanf.c, spawn.c, spawnve.c, spawnvp.c, statfs.c, textio.c: ++schwab
    Add 'const' to declarations where appropriate.
malloc.c:  ++schwab
    Make malloc() round all memory requests to the page size to be able
    to use all the available memory.
setjmp.cpp, setjmp.h: ++schwab
    Some cleanup; one element of jmp_buf[] can be saved by using the
    fact that signal 0 cannot be masked; why was the type char*[] insead
    of long[]?
osbind.cpp: ++schwab
    Add some missing functions added; code cleanup.
select.c: [e-mail]
    Fix select() to deal with timeouts of more than 65.535 seconds. This
    is needed for emacs 19.
statfs.c: ++schwab
    In statfs(): before passing to Dcntl, the path must be passed
    through _unx2dos, and it should be declared const.
sysconf.c: ++schwab
    Update the value returned for _PC_LAST.
fopen.c: ++schwab
    Make fopen() use 0666 as the default file mask (use umask() if you
    want something else); make mkdir() respect the umask setting.
mktemp.c: ++schwab
    mktemp() can generate a name more than once; the length of the
    pattern should not be changed (emacs depends on it).
lattice/crt0.s: ++pvt1-117
    Add some conditional stuff depending on program type.
utime.c: [e-mail]
    Pass through a NULL tset argument unchanged to the filesystem
    so that it can determine permissions correctly.
falcon.h: [e-mail], [e-mail]
    Change several erroneous macros to correctly cast return to short.
lattice/*: ++pvt1-117
    Strip all carriage returns from Lattice C files.
spawn.c: ++Ole_Arndt
    Add script interpretation (#!).
sync.c, support.h: ++Ole_Arndt
    NEW file, sync() and fsync() (for Minixfs only).  Proto in support.h.
sigactio.c: ++Ole_Arndt
    Use __NSIG instead of NSIG, may as well be POSIX-clean.
errno.h: ++Ole_Arndt
    Add errors ENOTDIR and ELOOP.
signal.h: [e-mail] (Ole Arndt)
    Fix definition of _SIGSET_MAX_INDEX to correct several bugs
    in the POSIX signal mask functions.
stdio.h:
    Add vsscanf() and _getbuf() protos (yech).
dirent.h:
    Add alphasort() proto (excluded by _POSIX_SOURCE).
utmp.c, wtmp.c, utmp.h:
    Rename write_utmp() to _write_utmp().  Rename write_wtmp() to
    _write_wtmp().  Add protos (and other cleanups) to utmp.h.
atof.c, fdopen.c, fputs.c:
    Move 'register' to beginning of declarations (shuts up gcc -Wall).
fwrite.c: ++michal
        With unbuffered IO fwrite miscounts number of characters written.
findfile.c: ++michal
    Try to accomodate tos style paths PATH=e:\bin,c:\bin,...
unistd.h: ++jrb
    Take out setlinebuf, doesn't really belong here.
ffs.c: [e-mail] (Michal Jaegermann)
    An even faster algorithm.  Yow!  Are we optimized yet?
support.h:
    Added _exit() and gethostname() protos. Removed write_utmp() and
    write_wtmp() protos.
lib.h, crtinit.c:
    Moved prototypes from crtinit.c to lib.h, and added more to lib.h.
abort.c, main.c, lib.h:
    Make abort() close file handles in exactly the same manner
    as exit().
sigactio.c, signal.h: [e-mail], ++Oskar, ++entropy
    Fix type of sa_mask in struct sigaction (sigset_t, not long).
    Clean up dirty tricks in sigaction() (UNTESTED).
falcon.h: [e-mail], ++entropy
    Add missing traps.
unistd.h, support.h:
    Cleaned unistd.h for easier reading.  Moved back the link(),
    symlink(), and readlink() protos from support.h (sorry if I seem
    really indecisive on where some of these protos belong).
doprnt.c, getdtabl.c, gethostn.c, mknod.c, nice.c, open.c, putenv.c,
symlink.c, utime.c:
    Include appropriate headers for protos (and fixed mknod() proto).
sys/statfs.h:
    Add statfs() proto.
sys/errno.h, sys/ioctl.h, sys/resource.h, sys/signal.h, sys/wait.h:
    Fix multiple-include protection to hopefully prevent possible
    infinite include loops (see Bugs file).
getpw.c, pwd.h: [e-mail] (Oskar)
    Use uid_t (_UID_T) for getpwuid() instead of int (POSIX).
lattice/inc.i: [e-mail]
    Fix a typo.

PATCHLEVEL34::

ffs.c: ++frog
    Much faster algorithm.
_fixsfsi.cpp, _fltsisf.cpp, frexp.cpp, modf.cpp,
Makefile: [e-mail] (Stefan Steyer)
    Bug fixes for SFP004 coprocessor code.  Add sfp004 targets.
doprnt.c: [e-mail] (Andreas Schwab)
    The decimal precision in a printf format does not include the sign or
    hex prefix, e.g. printf ("%-2.5d", -18) should print "-00018".
select.c, time.h: [e-mail], ++entropy
    Get struct timeval from time.h, eliminate local definition.
    Add prototype of select() to time.h (is there a better place?)
ctype.h, grp.h, dirent.h, stddef.h, string.h:
    Cleaned up for POSIX.
wait.h, pwd.h:
    Cleaned up for POSIX (need more work).
compiler.h, limits.h, stdio.h:
    Set stream limits for POSIX.
locale.h:
    Define NULL if not already defined (POSIX).
limits.h:
    Raise value of _POSIX_NGROUPS_MAX from 0 to arbitrary value of
    512 now that we have a decent getgroups().
fcntl.c, fcntl.h, errno.h:
    Add definition of F_SETLKW to fcntl.h.  Add ELOCKED to errno.h.
    If Fcntl() gets ELOCKED, return EACCES instead (POSIX).
unistd.h, stat.h, fcntl.h:
    Moved many prototypes to the correct headers.
sigactio.c, signal.h:
    Fix some violations of POSIX namespace.
stab.h, stab.def, Copyright:
    Symbol table definition files MOVED from gnu/ subdirectory to main
    include file directory.  Copyright message for these files added to
    Copyright file.

    Completely rewritten getgroups() function to replace the bogus one.
grp.c:
    Ignore spaces preceeding usernames in /etc/group.
main.c: ++Wolfgang
    Remove the non-macro versions of stdin, stdout, stderr.  It causes
    problems for some programs.  People doing debugging should know
    about _iob[] anyway.
setjmp.h: ++Wolfgang
    Fix some brain-damage in the BSD setjmp/longjmp from PL32.
types.h:
    Rearrange major() macro.
cuserid.c, stdio.h:
    NEW file, cuserid() function for SysV compatibility.
    Prototype and L_cuserid definition in stdio.h.

falcon.h: [e-mail], ++entropy
    Fix a typo in trap_14_wwwwww.  Add trap_14_wllll and trap_14_wlllll
    macros for DSP calls (UNTESTED).  Cast Dsp_Lock() to short instead
    of long.
chmod.c:
    For chown(), ignore EINVAL error so we don't get annoying errors
    on the TOS filesystem.
Makefile:
    Synch up with parts of jrb's TOS-library Makefile.
purec/install.bin: ++hohmuth
    Documentation update.
purec/makefile: ++hohmuth

    for Turbo C.
mincl:
    Don't compile libgcc2 with -mshort.

    Fix _isctty() for much better performance.
compiler.h: ++pvt1-117
    Add correct definition for __CDECL for Lattice C.
stat.h: [e-mail]
    Use mode_t instead of u_short for type of st_mode.
types.h: ++nox
    Do typedef time_t if _POSIX_SOURCE.  [I think my O'Reilly POSIX book
    mislead me on this one. -entropy]
sigactio.c:
    Give sigpending() a return value.  Oops.
ioctl.c:
    Include appropriate headers.
linea.c:
    Explicitly return the value for linea2() instead of magically
    using d0.
ffs.c, support.h:
    NEW file for BSD function ffs().  Proto in support.h.
sysvar.c: ++pvt1-117, ++entropy
    Add some typecasts to (hopefully) make Lattice C happy.
    [The patch I got did this differently, and in my opinion,
    in a more messy way.  Hopefully this is good enough -entropy]
lib.h: ++pvt1-117
    Remove findfile() proto, it is in support.h.
getrusag.c: ++pvt1-117, ++entropy
    Add a prototype _add_tval().

    is initialized.
chdir.c: ++pvt1-117
    Remove some dead code.

    A few typecasts here and there to keep Lattice C happy.
stdio.h: ++pvt1-117, ++entropy

    Cleaned up a bit for POSIX.
signal.h, unistd.h: ++pvt1-117, ++entropy
    Add prototypes for kill() and killpg() to signal.h.
    Remove kill() prototype from unistd.h.
getgroup.c, unistd.h: ++pvt1-117, ++entropy
    Use correct parameters for getgroups().
    Add prototype to unistd.h.

    Always return -1 with errno set to EINTR if MiNT's Pause() call
    returns without a longjmp() out of a signal handler.
support.h: ++pvt1-117, ++entropy
    Add protos for putenv(), _console_read_byte(),
    _console_write_byte(), _text_read(), _text_write(), getdtablesize(),
    write_utmp(), write_wtmp(), nice(), mknod(), fopenp().
mintbind.h: [e-mail]
    Fixes for Lattice C.

    Renamed gmakefil.16 and gmakefil.32 to GMakefile.16 and GMakefile.32.
Copyright:
    Renamed copyrigh.t to Copyright.
Files:
    Renamed common to Files.

PATCHLEVEL32::

sozobon/linea.s: ++dsb
    Prevent it from trying to redefine the Line-A variables that were
    already defined in alglobal.c.
support.h: [e-mail]
    Remove two occurances of the string "new" for C++ compatibility.
ctype.h:
    More POSIX namespace monkey business.
types.h:
    Made lots of stuff #ifndef _POSIX_SOURCE.  Added a few POSIX types
    (nlink_t, mode_t).
popen.c:
    I somehow managed to apply two patches to fix the close-on-exec flags
    for the child, without noticing.  Thanks to nox for pointing this
    out.  I think I've fixed it.
purec/makefile, purec/mintlib.prj: ++entropy
    Add ctermid.c to sources.
purec/makefile, purec/mintlib.prj: ++hohmuth
    Add switch for generating PC-relative function calls.
    Change default to assume the user does not have osbind.lib.
    PCREL stuff.  Add pgrp.c to sources.
purec/readme.pc, purec/install.src: ++hohmuth
    Updated documentation.
doprnt.c: ++hohmuth
    Make a long constant explicit for Pure C.
stat.c: ++hohmuth
    An error return value was missing (was return; is now return -1;).
statfs.c: [e-mail]
    Cast &mfsinfo to long, for Pure C.
setjmp.h:
    Implemented BSD-compatible _setjmp(), _longjmp(), setjmp(), and
    longjmp().  Selectable by defining _BSD_SOURCE.  BUG: not compatible
    with __STRICT_ANSI__.
fcntl.h:
    Add POSIX-required mask FD_CLOEXEC, to select the close-on-exec
    bit from the flags used in F_GETFD/F_SETFD fcntl().
sozobon/makefile: ++entropy
    Add ctermid.o and pgrp.o to targets.
unistd.h:
    Do not define prototype for getopt() if _POSIX_SOURCE is defined.
types.h:
    Do not #include <utime.h> if _POSIX_SOURCE is defined.
utime.h:
    Added prototype for utime().
main.c: [e-mail]
    The isatty status should be cleared for dumped programs.
float.h: ++schwab
    Update for GCC 2.4/enquire 4.3; the values for LDBL_{EPSILON,MIN,MAX}
    are computed with bc and verified with enquire.  The new values for
    {FLT,DBL,LDBL}_EPSILON seem reasonable, since enquire computes the
    right value for sozobon.
unistd.h:
    Changed BSD process group selection switch from _BSD_PGRP to
    _BSD_SOURCE.
stat.h: ++nox, ++entropy
    Added S_ISCHR(), S_ISDIR(), S_ISBLK(), S_ISREG(), S_ISFIFO(),
    S_ISMEM(), S_ISLNK(), S_IRWXU, S_IRWXG, S_IRWXO.
    (btw, is S_IMEM a typo of S_IFMEM or was that intentional?)
setjmp.cpp, setjmp.h:
    Implemented POSIX sigsetjmp() and setlongjmp().
ioctl.c, ioctl.h, pgrp.c:
    Implemented BSD's TIOCNOTTY ioctl, moved tty disconnection code
    out of pgrp.c.
sigactio.c, signal.h:
    Implemented POSIX signal set manipulation functions: sigaddset(),
    sigdelset(), sigemptyset(), sigfillset(), sigismember(),
    sigpending(), sigprocmask(), sigsuspend().
fopen.c:
    Always use O_NOCTTY flag in the call to open().
write.c:
    If Fwrite() returns 0 on a regular file, assume the disk is full
    and return -1 with errno set to ENOSPC.
errno.h, strerror.c:
    Add definition of EIO and ENOSPC.
read.c:
    If attempting to read from controlling terminal while backgrounded
    (e.g. while the tty is in a different process group), and SIGTTIN is
    ignored or blocked, return -1 with errno set to EIO.
isatty.c, support.h:
    Add new function _isctty() to determine if a file descriptor refers
    to the current process's controlling tty.  Prototype in support.h.
ttyname.c:
    Use L_ctermid instead of magic number 32 for length of
    ttyname() return value.
ctermid.c, stdio.h:
    NEW file, POSIX ctermid() function.  Prototype and constant L_ctermid
    in stdio.h.
doprnt.c: [e-mail]
    HSC choked on a string with implicit newlines (that is,
        "like
        this"
    as GCC is wont to do); I replaced it with explicit "\n"'s and string
    concatenation.
fread.c, fwrite.c: ++dsb
    Some judicious changes from size_t to unsigned long to allow reads
    and writes of >=64K with HSC.
getpw.c: ++dsb
    Minor tweak to work around a foible in HSC.
compiler.h: ++dsb
    Changes for HSC v2.00 and higher.
utime.h: ++dsb
    Changed "#endif _UTIME_H" to "#endif /* _UTIME_H */" to keep HSC
    from complaining.
sozobon/asm_pp.ttp, sozobon/asm_pp/*: ++dsb
    DELETED files; that functionality is provided via external programs
    now.
sozobon/readme, sozobon/makefile: ++dsb
    REPLACED files.
_addsubs.cpp, _addsubd.cpp, _div*.cpp, _mul*.cpp: michal
    Following some discussions with Olaf I rewrote addition routines to
    conform - at least here - strictly to IEEE spec.  As a matter of fact
    they even decreased in size. :-) Corrects handling various cased
    when you add or multiply infinities or NaNs.  To my best knowledge
    this now follows IEEE specifications, although do not quote me on
    that. :-) There is also some code rearangement in division routines
    to reduce unnecessary branching.  Thanks michal!
vdibind.h: ++jrb
    Change type of errorvar parameter from int * to short *.
errno.h: ++jrb
    Allow for inclusion into .cpp assembler files.
osbind.h: Markus Gutschke <[e-mail]>
    Stack adjustment amount was wrong. Was 6 should be 10. Thanks
    markus.
osbind.h: [e-mail]
    Wrong stack adjustment for trap_1_wwwll was 16 should have
    been 14. Thanks robert.
_cmpdf2.s, _cmpsf2.s: ++jrb
    DELETED files.
_cmpdf2.cpp, _cmpsf2.cpp: ++jrb
    NEW files.
open.c, fcntl.h:
    If controlling tty is "disassociated" from the process, the next tty
    device to be opened is the new controlling tty (unless O_NOCTTY is
    specified in the flags during the open()).  O_NOCTTY definition
    added to fcntl.h.
pgrp.c:
    Made a more reasonable attempt at setsid().  Kludge a way to
    "disassociate" the controlling tty by forcing fd -1 to /dev/null.
README:
    RENAMED readme to README.
Changes:
    RENAMED changes to Changes.
Bugs:
    RENAMED bugs to Bugs.
math-68881.h:
    RENAMED math-688.h to math-68881.h.  (It was already "really"
    named this, but I was running on a TOS filesystem).
PatchLev.h, ident.c:
    RENAMED patchlev.h to PatchLev.h.
Makefile:
    RENAMED makefile to Makefile.

PATCHLEVEL31::

statfs.c: [e-mail]
    Enhanced to get more information from minixfs.
unistd.h:
    Added pause() and sigpause() prototypes.  Changed prototype of
    setpgrp() to reflect new SysV-compatible version, and make proto
    apply only if not _POSIX_SOURCE.  Changed prototype of getpgrp() to
    reflect return type of pid_t (POSIX).  Added setpgid(), setsid(),
    _bsd_setpgrp() and _bsd_getpgrp() protos.  To access the BSD
    functions by their usual names, define the macro _BSD_PGRP (and do
    _not_ define _POSIX_SOURCE) before including unistd.h (for example,
    gcc -D_BSD_PGRP -c foo.c).
pgrp.c:
    NEW file, for process group related functions. Renamed setpgrp to
    _bsd_setpgrp().  Created new SysV-compatible setpgrp(). Created
    new BSD-compatible _bsd_getpgrp() (requires MiNT 1.03 or newer).
    Created new POSIX setpgid() and setsid().
getuid.c:
    Removed getpgrp(), setpgrp() functions.  See pgrp.c.
math-68881.h: ++jrb
    Sync up with gnu version.
math.h: ++jrb
    Change all #ifdef _M68881 to
    #if defined(_M68881) ||  defined(__M6881__)
    __M68881__ gets automatically defined when gcc -m68881.
doprnt.c: ++michal
    Still, so far I found two bugs in floating point support.  One
    was introduced by Howard when he tried to catch garbled results from
    floating point operations.  He caught in the process also negative
    zero and that was part of the reason why Scott got NaN.
    [in the part that check for overflows]
_divdf3.cpp: ++michal
    The other part was a wrong branch in a division routine which
    was giving a negative zero as a result of a division 0.0/1.0.
_divdf3.cpp, _divsf3.cpp:: ++michal, olaff
    Fixed sign for retinf, and retzero.
doprint.c:
    Undid my NaN fix; received a similar but not identical fix from bammi.
mintbind.h, osbind.h:  ++pvt1-117
    More changes to the Lattice C inlines.
findfile.c:  [e-mail]
    Added a new function buffindfile (like findfile, but with
    one argument more (the buffer to write the findname in)), changed the
    function findfile to call buffindfile.  Makes code work better with
    multi-threaded code.
spawnvp.c, fopenp.c:  ++Uwe_Ohse
    Use buffindfile instead of findfile and include support.h
    for prototypes.
spawn.c:  ++Uwe_Ohse
    Threw away some static arrays.
support.h:  ++Uwe_Ohse
    Added prototype for buffindfile.
eprintf.c:  ++Uwe_Ohse
    There was a static buffer which seemed pretty useless, so i
    changed the function to use a local buffer.
execp.c:  ++Uwe_Ohse
    Uses buffindfile instead of findfile.
main.c:  ++schwab
    Add initialization code for new G++ minimal support.
    Add non-macro versions of stdin, stdout, stderr for debuggers.
getcwd.c: ++schwab
    Remove kludge for broken GCC 1 optimizer since mintbind.h has
    been fixed and GCC 1 is no longer supported anyway.  Upgrade!
gbl-ctors.h, longlong.h, libgcc2.c: ++schwab
    NEW files.  G++ minimal support.
mincl:  ++schwab
    Use gcc2's "-x assembler-with-cpp" to compile the .cpp files,
    instead of doing the preprocessing in a separate step.
    NOTE:  IF YOU STILL USE GCC 1.XX, UPGRADE NOW!
    Also add support for several new files.
mincl:    [e-mail]
    Add missing rule for the 020 libraries.
doprnt.c:
    Fixed a bug reported by Helmut Kalowski and Robert Wilhelm.
    -0.0 and also 0.0/n for some values of n were being incorrectly
    printed as NaN.
purec/bios.s, purec/gemdos.s, purec/xbios.s: ++hohmuth
    Replaced files.
purec/readme.pc: ++hohmuth
    Update Ulf's address.

    Various changes.
osbind.h: ++hohmuth
    Remove most of the "Network Gemdos Extensions" cruft from the
    Turbo C section.
purec/install.src: ++hohmuth
    Small change in the docs.
purec/readme, purec/memcpy.c: ++hohmuth
    DELETED files.
purec/bcopy.s:    [e-mail]
    Faster algorithm, also replaces memcpy.c.

    Removed memcpy.c.
purec/makefile, purec/tosify.mak: ++hohmuth
    NEW files: for people who don't like the Pure C shell.
purec/install.src, purec/install.bin, purec/readme.pc:    ++hohmuth
    NEW files: updated documentation.
crtinit.c, spawn.c: ++hohmuth
    Implement extension to ARGV standard, allowing blank arguments.
aesbind.h, gemfast.h: ++bammi
    Rename MENU to MENU_T.  Add definition of WHITEBAK.  Remove ib_resvd
    element from ICONBLK.
minimal.h: ++bammi, ++schwab
    Add __main().
falcon.h, stdarg.h, varargs.h, compiler.h, mintbind.h, osbind.h: ++bammi
    Changes for GCC 2.
gnu/stab.def: ++bammi, ++schwab
    Replaced file.
gnu-out.h: ++bammi
    NEW file for the includes distribution, since more than just the GCC
    utils are using it now.
strlwr.c, strupr.c: ++bammi
    Use toupper() and tolower() instead of twiddling bits manually.
gmon.c: [e-mail], ++schwab
    Clean up prototypes for tick(), new C language mcount() for
    GCC 2.
lattice/bcopy.s, lattice/crt0.s, lattice/linea.s, lattice/setjmp.s,
lattice/vfork.s: ++pvt1-117
    Updated files.
symlink.c: ++hohmuth
    In readlink(), don't fail if filename is exact size of the buffer,
    use strncpy() to prevent writing past allocated buffer.
unx2dos.c: ++hohmuth
    Improved the _dos2unx() conversion scheme: we now produce file
    names which are more compatible to Posix.
    NOTE: The Posix file name can now become longer than the DOS file
    name!
symlink.c: ++hohmuth
    readlink()'s siz parameter is no longer passed on to
    Freadlink(), because DOS and Unix file names can be of different
    length.
stat.c: ++hohmuth
    Compute the correct size for symbolic links; some programs depend
    on it (namely Kenneth Almquist's bourne shell `ash').
unx2dos.c: ++hohmuth
    New routines _path_unx2dos() and _path_dos2unx(), for conversion
    of a list of file names.
lib.h: ++hohmuth
    Add prototypes for new _path_unx2dos() and _path_dos2unx().
main.c, spawn.c: ++hohmuth
    Added DOS<->Posix path conversion for all environment variables
    that are listed in the environment variable PCONVERT.  If PCONVERT
    does not exist, it defaults to "PATH".
main.c:    ++hohmuth
    The UNIXMODE interpretation code should ignore the parameter of
    the ".<c>" directive.  Fixed that.
lattice/bcopy.s, lattice/crt0.s, lattice/linea.s, lattice/setjmp.s,
lattice/vfork.s: ++pvt1-117
    Replaced files.
linea.h: ++pvt1-117
    Inlines for Lattice C.
lattice/inc.i: ++pvt1-117
    New file for Lattice C.
osbind.h: ++pvt1-117
    More inlines for Lattice C (Fsfirst() and Fsnext()).
ostruct.h: ++nox
    Make ibufhd and ibuftl (in _IOREC struct) volatile, so they are
    not incorrectly optimized.
wait.h: [e-mail]
    Add WIFCOREDUMPED(), WTERMSIG(), and WEXITSTATUS().
popen.c: [e-mail]
    Ensure parent's end of pipe gets close on exec, so child doesn't
    hang forever.
memccpy.c, memchr.c, memcmp.c, strchr.c, strrchr.c: ++schwab
    memcmp() should compare with unsigned char.  strchr(), strrchr()
    should not depend on signedness.  memccpy() and memcmp() simplified.
types.h: [e-mail]
    Add typedef for u_int, and add a makedev() macro.
realloc.c: [e-mail]
    In realloc, a block can only be split in two if there's enough room
    left for a struct mem_chunk (plus a bit more).
thread.c, support.h: ++boender, ++entropy
    Add prototype for tfork() in support.h, #include <support.h> in
    thread.c.
getpw.c, grp.c, grp.h, putpwent.c, pwd.h: [e-mail]
    New password aging code, support System V routines.
osbind.h, mintbind.h: [e-mail]
    Inline stuff for Lattice C.
wait.c, wait3.c, waitpid.c, wait.h: ++hohmuth, ++entropy
    Add prototypes for the waitxxx() functions, change definitions
    accordingly.  Follow the POSIX standard for definitions of these
    functions.
utime.c, ioctl.h: [e-mail], ++entropy
    Implement Julian's utime() patch.
sozobon/orig/*:
    Removed old files.
eprintf.c: [e-mail]
    _say()'s parameter is const; also add prototype for _say().
sleep.c: ++hohmuth
    Corrected signal handler's prototype, use long instead
    of __Sigfunc.
getcwd.c, times.c: ++hohmuth
    Added some casts to int for errno.
purec/*.prj, purec/readme: ++hohmuth
    Modified syntax of symbol definitions for assembler sources, for
    improved compatibility with Turbo C's assembler.
abort.c: [e-mail]
    Do not call exit(), use _exit() instead.
statfs.c: ++boender
    Add a kludge to get better answers on U:/PROC, U:/PIPE, U:/SHM.
sleep.c:
    Really fixed the problem with usleep() sleeping forever.
bsearch.c: [e-mail] (Juergen Lock), ++entropy
    Relax bug checking, return NULL for 0 parameters instead of
    assert()ing them to be non-NULL.
errno.h: [e-mail] (Andreas Schwab)
    New error, EPIPE.
fcntl.h: ++schwab
    Move internals of the library file I/O stuff to the library's
    "lib.h".
close.c, dup.c, ioctl.c, isatty.c: ++schwab
    Account for the above change.
_addsubd.cpp, _addsubs.cpp, _divdf3.cpp, _divsf3.cpp, _extends.cpp,
_fixdfsi.cpp, _fixsfsi.cpp, _fxunsd.cpp, _muldf3.cpp, _mulsf3.cpp,
_truncdf.cpp: ++schwab
    Use "bset #bitno,dn" instead of "orl #imm,dn" for speed.
    Fix a typo in _fixsfsi.cpp.
atof.c: ++schwab
    Fix a bug.
ctime.c: ++schwab
    [I don't understand this change, so I won't try to document it. -ent]
doprnt.c: ++schwab
    Fix 68020 version of _ICONV (divull arguments were reversed).
filbuf.c: ++schwab
    Set fp->_cnt = 0 on EOF or error.
fopen.c: ++schwab
    Don't close tty device if victim of freopen().  Also in freopen(),
    get a new buffer if file was closed.
ltoa.c: ++schwab
    #include "lib.h" once only.
popen.c: ++schwab
    Arrange for close parent's side of pipe in child process.  Free
    all used resources carefully.  Clean up linked list routines for
    pipe resource tracking.
strerror.c: ++schwab
    Add message for EPIPE.
strftime.c: ++schwab
    Fix typo in case 't'.  Initialize buf if format directive is
    undefined.
strtol.c: ++schwab
    Negating LONG_MIN gives overflow.
sysconf.c: ++schwab
    Pass argument to pathconf() through _unx2dos().
wait.c, wait3.c, waitpid.c: ++schwab
    Check for invalid signals (can result from Pterm(n) with n > 255).
    In waitpid.c, don't crash by recording status into NULL pointer.
    In wait3.c and waitpid.c, don't zero status->w_coredump.

PATCHLEVEL30::

purec/mintbind.s: [e-mail]
    Add bindings for Dgetcwd() and Salert() system calls.
crlf/crlf.c:
    Fix so it compiles on suns.
aesbind.h, vdibind.h, gemfast.h: ++jrb
    Changes for SpeedoGDOS and Falcon AES.
strlwr.c, strupr.c: ++jrb
    Made more robust.

PATCHLEVEL29::

sleep.c:
    It's up to the user, not the library, to make sure we don't lose by
    longjmp()ing out of a signal handler (and thus not restore our
    context correctly).  This simplifies things quite a bit, and fixes
    the annoying granularity of the PL28 version.
sleep.c:
    Fixed a bug, usleep(0) used to sleep forever (until interrupted)
    instead of no time.
purec/alloca.s, purec/*.prj, purec/readme: [e-mail]
    Rename STACK_CHECKING to STACKCH, for compatibility with Turbo C.
crtinit.c: ++hohmuth
    Add _PgmSize variable, featuring the total size of the program.
exec.c: [e-mail]
    Remove references to "extern char **environ", we can just pass NULL
    to spawnve() to get the current environment.  Remove functions
    execlp() and execvp() to reduce library drag.
execp.c: ++boender
    NEW file, containing execlp() and execvp(), previously in exec.c.
fork.c, getpid.c, kill.c, killpg.c, pipe.c, select.c, wait.c:
    Include <mintbind.h> instead of "mintbind.h", this should speed up
    your makes by a few milliseconds.
times.c:
    Fixed a small bug, errno wasn't being set correctly in one case.
makefile, mincl:
    Remove GLIB3 stuff, bammi says there's no getting around -lg++.
gnulib3.c, xyzzy.cc:
    DELETED files, bammi says there's no getting around -lg++.

PATCHLEVEL28::

a64l.c: [e-mail]
    Add to comments a note that prototypes are in support.h.
alarm.c: ++boender, ++entropy
    If requested time is greater than MiNT can handle, "round down" to
    (LONG_MAX/1000) seconds, to prevent unexpected "inquiry" calls to
    Talarm() (or even possible crashes).  This is only relevant if long
    integers are used, since (USHRT_MAX < (LONG_MAX/1000)).  Do NOT set
    errno if an error results (the only error that can be recognized,
    anyway, is that alarm() was called when MiNT was not active.  In
    this case, 0 is returned and no alarm is set.)
getpass.c:
    Read password from /dev/tty, instead of stdin, if MiNT is active.
link.c, symlink.c, support.h:
    Functions link(), symlink() now take "const char *" instead of
    "char *" parmeters.
getcwd.c: ++boender, ++entropy
    Use Dgetcwd() when running on MiNT 0.96 or newer.
limits.h: ++jrb ([e-mail])
    Fix definition of INT_MIN, evidently casting it to float didn't work
    with the old (equivalent) value.
stdlib.h: ++jrb
    Changed alloca macro for better parameter checking.
eprintf.c: ++jrb
    Make _say() a function instead of a macro.
fwrite.c, linea.c: ++jrb
    Some stuff I missed in patchlevel 26.
vdiesc1.h: ++jrb
    DELETED file, seems this was some leftover temp file, everything in
    it is already in vdibind.h.
access.c: ++boender, ++entropy
    Use real, not effective, user id's for access() checks.
    Fix so access() always returns success on existing files if real
    user id is 0 (root), regardless of file mode.
stat.c: ++ers
    Fix so stat("foo\\") is equivalent to stat("foo"), under TOS.
unx2dos.c: ++hohmuth
    Support unx2dos() and dos2unx() on non-GCC compilers (to the minimal
    extent to which they are supported on GCC).
sleep.c: ++entropy, ++boender
    Allow sleep() to be interrupted by signals under MiNT (0.95 or
    greater) by re-implementing with Psigpause() etc.
clock.c, getrusag.c, sleep.c, thread.c, times.c, time.h: ++boender, ++entropy
    Replace all occurrences of clock() with _clock(), temporarily
    alias clock() to call _clock() until we have something better.
times.c:
    Set errno and return -1 on error.
mintbind.h:
    Add new GEMDOS functions (macros) Dgetcwd() and Salert().
errno.h: ++boender
    Define ENODEV as alias for EUKDEV/EUNDEV.

PATCHLEVEL27::

isatty.c:
    Did some testing, it looks OK.  Fixed up the comments so
    it should be obvious how it works.
alloca.s, bcopy.s: [e-mail]
    RENAME to alloca.cpp, bcopy.cpp so we can do conditional compilation.
alloca.cpp, bcopy.cpp, bzero.cpp: ++dsb
    Changes for HSC.
mincl:
    Account for the name changes.
compiler.h: ++dsb
    Rearrange the __SOZOBONC__ #defines, fix a typo.
ctime.c, fscanf.c, sscanf.c: ++dsb
    Make compatible with HSC.
ident.c: [e-mail]
    Include patchlev.h instead of PatchLev.h since I zoo up the libs
    on a vanilla TOS filesystem.  This makes cross-compiling easier.
compiler.h: ++hohmuth
    define __TCC_GEMLIB__ when used with Pure/Turbo C
aesbind.h, gemfast.h: ++hohmuth
    Make it useable with Pure's GEM library.  The special declarations
    in aesbind.h check for __TCC_GEMLIB__.  Improved compatibility with
    Turbo's GEM declarations when __TCC_COMPAT__ is defined.
osbind.h: ++hohmuth
    Fix typos, add macros for sloppier type checking when used with
    Pure C.
strupr.c: ++hohmuth
    NEW file:  add library call strupr().
string.h: ++hohmuth
    Add declaration of strupr().
mincl, lattice/mincl.lcc, purec/mintlib.prj, sozobon/makefile:
    Add strupr.c.
doprnt.c: [e-mail]
    Fix up the ARG macro (which tends to produce wrong results with Pure
    C (which uses a type conversion scheme within ?: that differs from
    GCC)).
purec/*default*.prj: ++hohmuth
    The default project files now produce .ttp files by default.
purec/mint*.prj: ++ulf
    Use long distance jumps to call main().
purec/setjmp.s: ++ulf
    Save one more reggie.
purec/bcopy.s: ++(forgot who, sorry)
    Add symbol _bcopy.
dirent.c: ++hohmuth
    Avoid warning when compiling with __MSHORT__.
regexp.c: ++hohmuth
    Make it Turbo/PureC-proof.
ctime.c: ++hohmuth
    Add prototype for two_dig().
purec/bzero.c, purec/memcpy.c, purec/memset.c: ++hohmuth
    Moved files into purec/ since they are no longer in sozobon/.
purec/mintlib.prj: ++hohmuth
    Add a64l.c, account for moved files.
sozobon/makefile: ++hohmuth
    Add strupr.c.
falcon.h: [e-mail]
    Remove superfluous equals sign in enum declaration.
bugs: [e-mail]
    Many new entries.  Thanks, Hildo!
fread.c: ++ulf
    Fix return value for text mode.
times.c, times.h: ++ulf
    Use long return value instead of int.  This allows larger values
    and agrees with the SysV man page.
crlf/crlf.c, crlf/crlf.doc, crlf/Makefile:
    NEW files.  Program to strip (or add) carriage returns from (or to)
    test files.
*:
    Carriage returns stripped from all top-level files and all include
    files (files in sozobon/, purec/, and lattice/ not stripped).

PATCHLEVEL26::

changes:
    Rotated file to newest-first order.
readme:
    Added a few words of my own.
falcon.h:
    Protected against multiple #include's.
st-out.h: ++jrb
    Synchronized with bammi's version from incl85.
string.h:
    Added some parens to appease gcc -Wall with gcc 2.3.1.
getuid.c: [e-mail], ++entropy
    Only negative returns from Psetuid() and Psetgid() indicate
    an error.  Positive returns indicate success (the PID is
    returned from the OS).  Modified getuid() and setgid() accordingly.
_isnan.s: ++jrb
    NEW module from bammi's update27.
linea.h: ++jrb
    Applied bammi's patch from update27 (bammi's new address)
a64l.c: [e-mail]
    NEW module for conversion between longs and base-64 ASCII strings.
a64l.c: ++entropy
    Use __PROTO, use compiler.h, etc.
support.h:
    Added prototypes for a64l(), l64a().
bugs:
    NEW file.  Will be used as a sort of scratchpad for things that
    should be fixed.
common:
    NEW file to give an idea of what files are (or, rather, should be)
    the same in both the mntlib and bammi's toslib.
mincl: ++jrb
    Added _isnan.o to GLIB1.
mincl: ++entropy
    Added a64l.o to PORT.
makefile: ++entropy
    Added the -mbaserel libs to the default ("top") target.
    Added my personal setup in an ifdef.
_addsubd.cpp, _addsubs.cpp, _cmpdf2.s, _cmpsf2.s,
_divdf3.cpp, _divsf3.cpp, _extends.cpp, _muldf3.cpp, _mulsf3.cpp,
_negdf2.s, _negsf2.s, _normdf.cpp, _normsf.cpp, _truncdf.cpp,
atof.c, doprnt.c: ++jrb
    Synched with bammi's update27 and intermediate update.
support.h: [e-mail], ++entropy
    Fixed prototype for link().  Removed protoype for isatty()
    (it exists in unistd.h)
limits.h:
    Added #define PASS_MAX 8.
getpass.c:
    Fixed to use PASS_MAX, fixed off-by-one-error (was writing past end
    of static buf, very bad news).  Removed some small kludges.
fflush.c: [e-mail], ++entropy
    Return EOF instead of 0 for files that aren't open.
kill.c: [e-mail], ++entropy
    Allow negative pid's so process groups can be signalled.
isatty.c: [e-mail], ++entropy
    Only seek back to original position if fd wasn't a tty, to avoid
    OS overhead.  Don't bother setting errno, there's no point in
    doing so.  Old code had a comment saying it tries to seek forward
    one byte, but it was actually seeking to absolute position one.
    Now it does SEEK_CUR; hopefully this won't break it.

PATCHLEVEL25::

ioctl.h:
    ANYP means "no parity", not "any speed"
wtmp.c: [e-mail]
    If we're going to write to a file, we
    really should open it for writing, not reading!
difftime.c: [e-mail]
    The parameters were reversed. Ouch.
bcmp.c: [e-mail]
    Change the ODD macro to return a 16 bit value (for
    Pure C)
crtinit.c:
    Changed the "switch(_stksize)" statement into an
    if-then-else (apparently PureC can have troubles
    with a long in a switch statement).
purec/: [e-mail]
    Updated documentation for the unixname program,
    and provided source code.
open.c:
    Modified to use the kernel's O_APPEND when appropriate.
spawn.c: [e-mail]
    Fixed an off-by-one error in the command line calculation
    stuff.

Changes from Andreas Schwab ([e-mail]):
* compiler.h: for gcc2, use the builtin sizes
* gemfast.h: add XCONTROL messages and WF_COLOR defines
* mintbind.h, osbind.h: add the missing definitions
* rusage.h: fix typo, add <time.h> for struct timeval
* screen.h: fix definitions for TT
* stdio.h: allow 32 open files as does MiNT
* stdlib.h (alloca): avoid cpp warning, nearly all GNU programs define
    it unconditionally
* termcap.h: fix typo
* wait.h (WSTOPPED): use expected value

select.c:
    Fixed the parameters (they were supposed to have type
    "long *" rather than "long").
dirent.[ch]:
    Fixed a very bogus use of the Dreaddir() return value,
    which in fact is a magic cookie that can't be used!

various places:
    Applied bammi's updates (thanks, bammi!)
