[Gm2] latest cvs changes

[Gaius Mulley]

Hi,

here are the latest changes entered into the cvs:

   * gm2/lang-specs.h:  create modulename_m2.cpp init file if
     -g is present on the command line.
   * gm2/TODO:  removed completed item on the list.
   * gm2/gm2-compiler/M2GenGCC.mod:  convert constants to
     integer if they are to be passed to a C stdarg function.
   * gm2/gm2-compiler/M2Quads.mod:  pass the address field
     of an unbounded array if it is an argument to a
     C stdarg function.
   * gm2/gm2-compiler/M2GenGCC.mod:  removed function
     DefaultCStdArgPromotion and fixed test code.
   * gm2/gm2.texi:  documented behaviour of stdarg parameters.

The most obvious user level change is that it is easier to debug an
application now as the automatically created cpp file containing
main() is created in the current directory (rather than /tmp).

The name of the initialisation file is modulename_m2.cpp when -g is
present during linking.

regards,
Gaius
