Looking at my backups of 2001 (god bless backups...) I found that
the running kernel when I built my glibc (yes, I still use the same
glibc that in 2001...) was 2.4.10, so I'm going to replace the
symlinks with two real dirs with the headers from 2.4.10. Thanks a
lot for your help :)

Yes :(( I hope that in the next version that is fixed (and the
fact that the libc cannot be compiled with newer versions of GCC
because of an stupid bug in a prototype, but that's a very offtopic

If I ever write a kernel module, I won't ;) Thanks for your help
