 * 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.
