This thing's running RHAS2.1 which I think dates from before the invention of the transistor. Running home-made gcc-3.3.2 and binutils-2.14.90.0.6-1. I'll send along the three elf.h's under /usr/include. > 2) I also like to know if other architectures broke - so I can figure > out how to fix this. Dunno yet - I didn't do the normal batch of cross-compiles due to spending six hours chasing down new bugs. > I have tested this on X86_64/amd64 (gentoo based) only. That fixes the modpost.c compile, but the new futex stuff fails because ia64 doesn't implement ptr_to_compat(). In fact only three architectures appear to do so.
