endian.h is part of glibc (in 2.3 and 2.7 that I've checked) and can be found in the /include directory. It typically includes bits/endian.h, which in turn references system dependent files deeper down.

I have modified cpp/include/IceUtil/Config.h to reflect the constants defined in endian.h. This compiles the files - I still have to get all the 3rd party libraries built, so I can't link it yet. But I think this is heading in the right direction.

I'll complete the work & let you know it goes. Are there any documents to help me with cross-compiling Ice? I've a lot of experience at doing it with fairly tricky apps, like Python & ACE, but it always helps if there's some specific documentation.

My cross development environment is GCC-4.2.3, GLIBC-2.7 with NPTL & TLS.
