Hmm, the sources currently use three different ways to detect endianess: 1) WORDS_BIGENDIAN (which appears to be an autoconf thing actually, enabled via AC_C_BIGENDIAN, which we never call currently) 2) __BTYE_ORDER == __BIG_ENDIAN which appears to be be defined in endian.h always by glibc 3) __BIG_ENDIAN__ appears to be quite common too? gcc thing? Also this: http://sourceforge.net/p/predef/wiki/Endianness/ We should probably stick to one of these things. Probably #2 or #3... I can't find any normative documentation about these things. Given that the #2 is at least unconditional part of glibc, I'd say to convert everything to that. Would that work for you on ppc-be too?
