Sure, I'm fine with that myself.  Let's see if anyone has objections, if
not I'll try a test build and see if anything needs fixing.

Not everything uses GNOME_COMPILE_WARNINGS, but that's not a big deal -
my main goal here is to in order:

1) Convince module maintainers not to use -Wall -Werror
2) Ensure we *do* use -Werror=format-security and the other core ones.
   That one is often injected by distributions right now, and it only
   therefore potentially gets noticed fixed after release when tarballs
   are rolled or whatever.
