We expect a reversed range to make grep give a diagnostic and exit 2.
With glibc (--without-included-regex), you get no diagnostic and exit 1.

OK, following the gnulib change at http://lists.gnu.org/archive/html/bug-gnulib/2010-02/msg00006.html and subsequent bug report at http://sourceware.org/bugzilla/show_bug.cgi?id=11244 I've come up with the attached patch (against the latest snapshot). It results in grep using Glibc's regex implementation and all tests pass.

However, I will admit (hopefully before the laughter starts!) that I'm not an experienced C coder, so the patch might just be a fluke! I am certainly more than happy to receive constructive criticism on its contents or format though.
