Work around GCC and GNOME bugs when --enable-gcc-warnings.

Browse source 
* emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
to work around GNOME bug 683906.
* image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
(struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
This works around GCC bug 54561.
