-
- Here is the listing of changes from patch.txt for the first patch v7.0a.
- Hope this helps.

-
- =======================< WHAT HAS BEEN FIXED? >=======================
-
- The patch modifies the following components:
-
- LINK
- LIB
- IMPLIB
- PWB (including PWB.EXE and PWBUTILS.MXT)
- CV and CVW (including the DLLs)
- CVPACK
- TRACE
- TXTONLY.OBJ
- GRAPHICS.LIB
-
- Part 3 lists all the affected files. The following sections
- describe the fixes to each component.
-
- LINK (version 5.31.009) Fixes
- -----------------------------
-
- - Fixups of MOVE overlays no longer incorrectly generate
- error L1101 ("invalid object module") if a thunk is targeted
- into the same overlay.
-
- - The linker no longer overflows internal tables if a large
- number of MOVE overlays are requested.
-
- - Data items defined as dw<?> are no longer incorrectly
- initialized to zero in the presence of overlapping virtual
- memory areas.
-
- - The linker is no longer prevented from generating correct
- "unresolved external" error messages if a program uses
- APPLOADER in the .DEF file.
-
- - The linker no longer creates an executable file that fills
- available hard disk space, an error that occured only
- when [1] two symbols in the same .OBJ file differed only in
- capitalization (for example, ExtraBytes and EXTRABYTES),
- [2] you linked with /CO and not with /NOI, and [3] the
- symbols were defined in an order that created a COMDEF
- record for the first one and a PUBDEF for the second.
-
- - The linker no longer incorrectly generates errors when
- linking MOVE overlays that include .OBJ files compiled with
- the /Gy (use Comdats) option.
-
- - The linker no longer incorrectly generates error L1035
- ("error in module definition file) in cases where [1] a
- FUNCTIONS statement appeared first in the .DEF file, or
- [2] new PRIVATE or PRIVATELIB statements were added to
- a LIBRARY statement.
-
- - New warning L4059 has been added. It occurs if code
- contains far segment references to overlaid targets. These
- references are resolved correctly only if they are code
- references (not data references).
-
- - New warning L4087 has been added. It warns that the /DYNAMIC
- option disables /EXEPACK. The linker now ignores /EXEPACK
- for MOVE applications, preventing previous problems in
- executables linked with /DYNAMIC and /EXEPACK.
-
- LIB (version 3.20.010) Fixes
- ----------------------------
-
- - LIB now correctly handles a symbol with more than 128
- characters in its name.
-
-
- IMPLIB (version 1.40.005) Fixes
- -------------------------------
-
- - IMPLIB now correctly handles a symbol with more than 128
- characters in its name.
-
- PWB (version 2.1.49) Fixes
- --------------------------
-
- - PWB no longer causes unexpected link errors when you try to
- build a project after trying to customize a project template.
- This condition occurred if you had tried to use the Customize
- Project Template dialog and all additional libraries were
- removed from the link options.
-
- - PWB no longer causes fatal error U1095 ("expanded command
- line too long") if you use the library template with a large
- number of OBJ files in a project file.
-
- - PWB's project mechanism no longer reports errors if PRELOAD,
- FIXED, DISCARDABLE or LOADONCALL appear in your .RC file. To
- take advantage of this fix, be sure to delete your existing
- PWB status file (CURRENT.STS) located in the directory
- specified by the INIT environment variable.
-
- CV and CVW (version 4.01) Fixes
- -------------------------------
-
- - It is now possible to set a breakpoint inside the Windows
- kernel (particularly, USER.DLL and GDI.DLL).
-
- - It is now possible to set a breakpoint on a Windows API
- routine (for instance, GlobalAlloc).
-
- - CodeView no longer causes a UAE when loading user DLLS.
-
- - The CodeView user interface no longer causes UAEs.
-
- CVPACK (version 4.01) Fixes
- ---------------------------
-
- - CVPACK no longer prevents linking of certain executables
- containing .OBJ files with CodeView information generated
- by C 6.0 and C/C++ 7.0.
-
- TRACE (version 1.1) Fixes
- -------------------------
-
- - TRACE /E now recognizes the executable CV format.
-
-
- TXTONLY.OBJ Fixes
- -----------------
-
- - TXTONLY.OBJ no longer causes a link error when a program
- calls _clearscreen. (TXTONLY.OBJ is used to reduce the
- size of executables that use only text modes and do not
- change the pallette.)
-
-
- GRAPHICS.LIB Fixes
- ------------------
-
- - The _outtext and _outmem functions now behave correctly
- in text mode on CGA systems.
