Okay, someone tell me how exactly you're building glib with c89, on
what operating system.  It fails for me here on RHEL6 (gcc (GCC) 4.4.4
20100726 (Red Hat 4.4.4-13)), if I specify -std=c89 in CFLAGS:

It looks to me like we also need to specify at least _POSIX_SOURCE
defined, but even that's not good enough because we need va_copy,
which requires -D_GNU_SOURCE.   Hmm, actually doing this breaks half
the configure checks if we just specify it on "make" invocation,
because we find "va_copy" during detection since we're using the
default gnu89.

If I manually run configure like:
./configure --prefix=/src/build/jhbuild
--libdir=/src/build/jhbuild/lib64 CFLAGS='-Wall -std=c89'

then it errors out later trying to find arpa/nameser_compat.h.

So...if people are claiming this really works, let me know how you're
doing it...
