The outcome of AC_C_BIGENDIAN isn't used on OSX. Depending on the exact version you look at, things might work differently; in trunk, Include/pymacconfig.h should be used, which does #if defined(__APPLE__) # undef WORDS_BIGENDIAN #ifdef __BIG_ENDIAN__ #define WORDS_BIGENDIAN 1 #endif /* __BIG_ENDIAN */ #endif Earlier versions included that ifdef block directly in pyconfig.h.in. In case it isn't clear how this works: GCC predefines __BIG_ENDIAN__ on PPC but not on x86; for universal binaries, two (or more) separate preprocessor (and compiler runs) are done.
