Hi Scott,

finally I've tracked down a poisoned symbol which delayed the
implementation of this feature.  M2RTS_HALT now accepts an optional
exit code using the optional parameter language extension.

The latest changelog entries are:

   * gm2/gccgm2.c:  added garbage collector tags to
     all tree structure fields.  Use local variable, s,
     rather than, t1, in global_constant.
     New function (gccgm2_DumpGlobalConstants).
     Dont pushdecl constants as they are placed onto
     the global_binding_level and never deallocated.
   * gm2/examples/gravity/twoDsim.mod:  intemediate checkin.
   * gm2/gm2-compiler/M2GCCDeclare.mod:  changed debugging
     watch symbol.
   * gm2/gm2-compiler/SymbolConversion.mod:  corrected
     misleading internal error message.  Only poison
     non constant symbols as constants remain declared
     in the global_binding_level.
   * gm2/gm2-libs/M2RTS.def:  HALT now has an optional
   * gm2/gm2-libs/M2RTS.mod:  implement optional parameter
     (exit code).
   * gm2/gm2-libs/StdIO.def:  added new line.
   * gm2/gm2-libs-ch/StdIO.c:  changed HALT extern.
   * gm2/gm2-libs-iso/M2RTS.def:  HALT now has an optional
   * gm2/gm2-libs-iso/M2RTS.mod:  implement optional parameter
     (exit code).
   * gm2/ulm-lib-gm2/std/M2RTS.mod:  implement optional parameter
     (exit code).
   * gm2/www/  fixed apt/sources.list information for
     the latest binaries of gm2.  Also fixed release numbers.
   * gm2/p2c/p2c-src/src/lex.c:  change getline to
     pgetline to avoid a name clash with
     /usr/include/stdio.h.  Call pgetline rather
     than getline.
   * gm2/p2c/p2c-src/src/parse.c:  call pgetline
     rather than getline.
   * gm2/p2c/p2c-src/src/decl.c:  allow HALT to
     take an optional exit code parameter.  If absent
     the parameter defaults to -1.
   * gm2/p2c/p2c-src/src/funcs.c:  modify the parsing
     of procedure declarations to allow an optional
     parameter using the GNU Modula-2 syntax.
   * gm2/p2c/p2c-src/src/trans.c:  tidied up dates in
