Ah, OK.

The documentation of G_GNUC_FUNCTION and G_GNUC_PRETTY_FUNCTION
does not mention any of this. I have some debug prints that do

	g_message ("%s: foobar", G_GNUC_FUNCTION);

and suddenly are much less informative :-(

No problem for me, I can change those. But I suspect other
people will have the same problem, now that Debian unstable
has made gcc-3.2.2-pre the default system compiler.
