I find this a bit weird. A C program has to know the architecture in order 
to include the right endian.h? Is there no header that already implements 
this logic?

Don't worry too much. Just make it work for yourself. If someone else wants 
to build Haiku on Darwin PPC he'll simply have to have a look.

Probably <regex.h>. :-P Good luck!

BTW, for build related stuff you can as well mail me privately. I guess 
most of this list's subscribers aren't interested that much in the details.
