I wondered if there should be some startup-time sanity check of that, just to be safe. The current GCC sources indicate that it'll define __BIG_ENDIAN__ on big-endian IA64 targets. It may be good to add __BIG_ENDIAN__ and __LITTLE_ENDIAN__ to the list of macros we test for; certainly several GCC configurations seem to define one or the other for several processors that can go either way. I'll take a look.... Ken
