It is in the file gtk.m4 which comes with GTK+. On a Linux system, it is
automatically installed in /usr/share/aclocal. GIMP has it in its
aclocal.m4 file because that's the way how automake packages are
distributed. If your aclocal script can't find gtk.m4, you can use the
"-I /path/to/directory/with/gtk.m4/file" flag with aclocal, or you can
append gtk.m4 to acinclude.m4. After you run aclocal, autoconf and
automake are able to find the macros.

If you bug me long enough with this, I'll write a FAQ entry before I go on
holidays ;-).

This is in my opinion a "deliberately broken package". They'd better
install the binary (because that's exactly what the gtk-config script is)
in a separate --exec-prefix'ed directory and document that you should use
the "--with-gtk-exec-prefix" flag to specify which version to use. For
convenience, you could even set a softlink to the most used GTK version.
Been there, done that (on IRIX 5.3 and 6.[2345]).

That doesn't help. AM_PATH_GTK just tries to find gtk-config, there's no
way to specify that the config script has another name.
