- * Library Configuration Definitions.

- * This file defines the default configuration for the library.
- * If the target system does not have make or a way to specify
- * #defines on the command line, this file can be edited to
- * configure the library. Otherwise, one can override portability
- * and configuration-related definitions from a Makefile or command
- * line by defining FEATURE_SUPPORT and COMPRESSION_SUPPORT (see below).

-
- /*
- * General portability-related defines:
- *
- * HAVE_IEEEFP define as 0 or 1 according to the floating point
- * format suported by the machine
- * BSDTYPES define this if your system does NOT define the
- * usual 4BSD typedefs u_int et. al.
- * HAVE_MMAP enable support for memory mapping read-only files;
- * this is typically deduced by the configure script
- * HOST_FILLORDER native cpu bit order: one of FILLORDER_MSB2LSB
- * or FILLODER_LSB2MSB; this is typically set by the
- * configure script
- * HOST_BIGENDIAN native cpu byte order: 1 if big-endian (Motorola)
- * or 0 if little-endian (Intel); this may be used
- * in codecs to optimize code
- * USE_64BIT_API set to 1 if tif_unix.c should use lseek64(),
- * fstat64() and stat64 allowing 2-4GB files.
