  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.
