It seems configure fails on RHEL5 vintage autoconf

Yuck. I'll take a look (it may be that older autoconf has a bug, and I
merely need to backport a workaround for that bug fix).
I'm guessing it is the gl_WARN_ADD() macro that is at fault
somehow.
Very possible, in fact, it may be a case of gl_WARN_ADD using an
autoconf macro and assuming newer semantics, where a bit more work is
needed to guarantee support with autoconf 2.59.
