Subject: [PATCH] Avoid compiling autoconf test programs with -Wall -Werror;
 doing so causes trouble on Ubuntu, where the Gtk test programs don't check
 the return value from system() and thus fall foul of the combination of our
 -Werror and <https://wiki.ubuntu.com/CompilerFlags#-D_FORTIFY_SOURCE=2>.
