[Gm2] latest CVS changes

[Gaius Mulley]

Hi,

here is the latest changelog entry.

     * fixed set type debugging information.
       Many changes to gm2/gccgm2.c and
       minor changes to gm2/gm2-compiler/M2GenGCC.mod.
       Debugging set types with gdb now works if -gstabs
       are used on the command line of gm2 and also the
       modified gdb-6.3 is used.

I'll be uploading the modified gdb-6.3 tarball later this evening.
The modifications include basic set type handling and type
descriptions are written out in Modula-2 syntax rather than say C.
You need to enable the Modula-2 mode by:

(gdb) set lang modula-2

from within gdb. The gm2 compiler needs to have -gstabs present on
the command line (dwarf seems broken - maybe a bug in gm2 or gcc I'm
not sure).

Enjoy,
Gaius
