WARN_CFLAGS was already used in gtk/engine/Makefile.am, but not initialized by configure.
For backwards compatibility, GCC's by default is very permissive. In my case, it was silently miscompiling code which was calling a non-existent GTK function. For this particular case, the proposed WARN_CFLAGS should make the build fail early in this case. I'm not proposing -Werror because it frequetly results in broken builds for trivial reasons when distros update the toolchain.
