40 * General portability-related defines:
41 *
42 * HAVE_IEEEFP		define as 0 or 1 according to the floating point
43 *			format suported by the machine
44 * BSDTYPES		define this if your system does NOT define the
45 *			usual 4BSD typedefs u_int et. al.
46 * HAVE_MMAP		enable support for memory mapping read-only files;
47 *			this is typically deduced by the configure script
48 * HOST_FILLORDER	native cpu bit order: one of FILLORDER_MSB2LSB
49 *			or FILLODER_LSB2MSB; this is typically set by the
50 *			configure script
51 * HOST_BIGENDIAN	native cpu byte order: 1 if big-endian (Motorola)
52 *			or 0 if little-endian (Intel); this may be used
53 *			in codecs to optimize code
54 * USE_64BIT_API	set to 1 if tif_unix.c should use lseek64(),
55 *                      fstat64() and stat64 allowing 2-4GB files.
