Yes, it is confusing to have --disable-werror compilations break because
of warnings becoming errors.  However, the subject is imprecise, what about:

configure: Allow builds with extra warnings

The clang compiler supports a useful compiler option -Weverything,
and GCC also has other warnings not enabled by -Wall.

If glib header files trigger a warning, however, testing glib with
-Werror will always fail. A size mismatch is also detected without
-Werror, so simply remove it.
