[Gm2] latest CVS changes

[Gaius Mulley]

Hi,

I've just checked in the following changes into the CVS.

        * gm2/Make-lang.in:  added rules for M2Swig.def and
          M2Swig.mod.
        * gm2/lang.opt:  added new option -fswig.
        * gm2/gm2-compiler/M2Code.mod:  import GenerateSwigFile
          and call it appropriately.
        * gm2/gm2-compiler/M2GCCDeclare.mod:  improved debugging
          of subranges.
        * gm2/gm2-compiler/M2Options.def:  added GenerateSwig.
        * gm2/gm2-compiler/M2Options.mod:  implemented case to
          test for -fswig which sets GenerateSwig to TRUE.
        * gm2/gm2-compiler/SymbolTable.def:  export
          IsParameterUnbounded, IsParameterVar.
        * gm2/gm2-compiler/SymbolTable.mod:  implemented above
          procedures.
        * gm2/init/gm2-gccinit:  added reference to M2Swig.
        * gm2/examples/swig/{full-strlib,strlen,strlib}:  new
          directories.
        * gm2/examples/swig/full-strlib/{Makefile,testcopy.py,
          testequ.py,testlen.py}:  new files.
        * gm2/examples/swig/strlen/{Makefile,StrLib.def,StrLib.i,
          StrLib.mod,testlen.py}:  new files.
        * gm2/examples/swig/strlib/{Makefile,StrLib.def,
          StrLib.mod,testlen.py}:  new files.
        * gm2/gm2-compiler/M2Swig.{def,mod}:  new files which
          implement an automatic way of producing swig interface
          files from an implementation module.

        * gm2/gccgm2.c:  skip_type_decl in build constructor
          functions.
        * gm2/gm2-compiler/M2GCCDeclare.mod:  handle subscripts
          in PrintVerbose routines.
        * gm2/gm2-compiler/M2GenGCC.mod:  detect unbounded
          arrays of generic type and use memcpy rather than
          assignment.
        * gm2/gm2/gm2-compiler/M2Quads.mod:  improved error
          messages for unknown types at the end of functions.
        * gm2/gm2/gm2-compiler/M2System.def:  export
          IsGenericSystemType.
        * gm2/gm2/gm2-compiler/M2System.mod:  implement
          IsGenericSystemType.
        * gm2/gm2-compiler/SymbolTable.def:  export
          IsPartialUnbounded.
        * gm2/gm2-compiler/SymbolTable.mod:  implement
          IsPartialUnbounded and added PartialUnbounded
          cases to GetSymName and GetDeclared.
        * fixed bug reported by James Cox.

        * gm2/gccgm2.c:  build_common_tree_nodes requesting
          unsigned char type.
        * gm2/gm2-compiler/M2GenGCC.mod:  CalculateBase
          must not assume GetType(Subscript) will always yield
          a subrange.
        * gm2/gm2-compiler/M2GCCDeclare.mod:  likewise
          must not assume GetType(Subscript) will always yield
          a subrange (the array might be declared as ARRAY CHAR
          OF CHAR).
        * testsuite/gm2/pim/run/pass/For9.mod:  new file.
