Hello,
I've just bootstrapped, configured with --enable-gcc-warnings, built
and run "make check" on Fedora 15 (i.e., gcc version 4.6.0 20110413)
I was surprised to see so many failures (abbreviated output below).
However, they're all due to one newly-enabled gcc warning:
note the [-Werror=unused-but-set-variable] in every case below.
At first I tried to turn off only that one new warning,
but -Wno-unused-but-set-variable had no effect, so I
resorted to -Wno-unused. In case you want precisely that
change, here's a patch. With this, all of the tests passed.

Subject: [PATCH] avoid spurious test failures due to new gcc warnings
* configure.ac (WARN_CFLAGS_TEST): Disable -Wunused, to
avoid many spurious test failures when using gcc-4.6.0
and when configured with --enable-gcc-warnings.
