[Gm2] cvs latest changes

[Gaius Mulley]

Hi,

here are the latest changes on the 4.1.2 branch of gm2:

    * gm2/gm2-compiler/PCSymBuild.mod:  fixed bug in deduceTypes
      so that binary constant expressions can correctly identify
      their types.  Fixes a bug report by Scott Iverson.

    * gm2/gccgm2.c:  gccgm2_GetArrayNoOfElements (New function).
    * gm2/gm2-compiler/M2GenGCC.mod:  checkArrayElements (New
      procedure function).  CodeBecomes modified to call
      checkArrayElements to test whether assigned arrays contain
      the same number of elements.
    * gm2/gm2-compiler/M2Quads.mod:  CheckBecomesMeta tidied up
      error messages and added extra check to ensure that
      we are not assigning from an unbounded array.
    * gm2/gccgm2.def:  export GetArrayNoOfElements.
      Fixes a bug reported by Scott Iverson.

regards,
Gaius
