GRUB recently switched to -Werror because this helps detecting bugs that could
otherwise be very difficult to debug (e.g. memory corruption).

For now, what we're doing is override AC_LANG_PROGRAM in aclocal.m4.  Untill
you find it suitable to require a C89 compiler, is there any better option for
us to continue using -Werror?  (I find a macro override less hassle than
playing with temporary CFLAGS)
