Standard C doesn't provide any such things. What we're having is a WORDS_BIGENDIAN define which is set on big endian machines and undefined on little endian machines. which we use in some places to do manual conversions: http://lxr.php.net/opengrok/search?q=&project=PHP_5_3&defs=&refs=WORDS_BIGENDIAN&path=&hist= > >> 2) Can anyone recommend a cheap way to gain access to a Big-Endian machine > >> for development and testing? > Ugh.

They all provide x86 hardware as modern big endian gear is relatively expensive and not what most people expect. Sun provided a test machine though (see also private mail) while currently I can't provide accounts there. johannes
