I tried that, but still have no mention of _GNU_SOURCE in my config.h.

I also did a `find-grep-dired' for gl_EARLY in /usr/share/autoconf and
/usr/share/automake-1.10: no occurrences found at all.

Where is gl_EARLY supposed to be defined?  Once I know that, I can
dig deeper about what's not working in my system.
