Well, in most cases Glibc 2.0 doesn't include errno.h either.
Actully this particular case is a bug in Glibc2.1 -
pthread_mutex_trylock() is defined to return EBUSY when the mutex
is already locked. This is a pthread API component and has nothing
whatsoever to do with errno, so the requirement to include errno.h
is a brokenness IMHO.

If you are compiling debian source packages that someone else built
they are broken. If you are creating binary debian packages yourself
I see the point however. We should probably add a --with-uninst-gii
flag to the LibGGI configure script.
