I already mentioned this in

	http://gcc.gnu.org/ml/fortran/2004-05/msg00259.html

but failed to provide a proper bug report due to many other problems with
libgfortran on all of my platforms.

Certainly: libgfortran cannot unconditionally assume the presence of a ISO
C99 C library, or else it would be useless with all but recent versions of
glibc.
