But they *are* used in gtk3 right now...

I totally agree with this.

But the point is, if something's not tested, it's basically guaranteed
to break (like srcdir != builddir, etc).  gcc defaults to enabling GNU
features, and the buildbots don't specify -std=c89, so there is
absolutely zero testing coverage.

If we want this to work, we need to add stuff to configure.ac in
modules to, if gcc is detected, add -std=c89.  Or we tell people to
use gnu89, and other compilers have to implement the GNU C subset we
make up (which is apparently C++ comments OK, nested functions not OK,
etc).
