I took another look at this.

The GCC bug was https://gcc.gnu.org/bugzilla/show_bug.cgi?id=38958,
fixed in GCC 4.9.  That seems pretty old...

I updated my warning.m4 patch to try to disable -Wunused-variable when
the compiler fails a test for this bug.  However, my try runs still
fail.  I'm going to take another attempt at it, using a hack to get the
configure logging output into the file that's visible in buildbot, since
I didn't see a way to fetch the config.log.
