Aha! Hard fact (well almost).
So one can make it work using gcc. I sort of suspected that was possible.
That wasn't my point, really. Is it a good idea to tie gnome/gtk to gcc? I
don't think so myself.
FWIW, I compiled Gtk+ with g++, and my computer is still working, so far
as I can tell. The libraries have gotten  bigger though ~2.1M -> ~3.5M.

A brief rant:
GTK+ is written in C, for reasons I understand and agree with.
However it is pretty new code, so why do people use C++ keywords all over
it? 
Come on, that's avoidable.
I had to compile gdk with -Dclass=klass -Dprivate=Private on the CFLAGS,
and fart around with extern "C" declarations quite a bit.
It generated thousands of warnings, mostly from uncasted conversions from
void* to other pointers, but I can live with those.
