        * libgimp/gimp.[ch]: gimp_main now takes a GimpPlugInInfo *,
        and PLUG_IN_INFO is now a static variable set from that. This
        removes all the special casing for the Win32 and OS/2 ports around
        this. Also added a debugging hook for quit procs.

        * plug-ins/common/mng.c: moved MAIN() to the end so PLUG_IN_INFO is
        declared.

        * plug-ins/gimpressionist/gimpressionist.c: pass &PLUG_IN_INFO
        to gimp_main.

        * plug-ins/pygimp/gimpmodule.c: Here too. Also add a message
        function.
