34 | * configure the library. Otherwise, one can override portability | |

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 | |
