here are the latest cvs changes:

2012-04-11      Gaius Mulley <address@hidden>

        * gm2/gm2-compiler/M2GCCDeclare.mod:  (DeclarePackedSet) New
        * gm2/gm2-compiler/SymbolTable.mod:  (MakeSet) creates an
          equivalent packedInfo placeholder.  (MakeEquivalent)
          and (GetPackedEquivalent) modified to handle set type.

2012-04-07      Gaius Mulley <address@hidden>

        * gm2/gccgm2.c:   (calcNbits) New function.
        * gm2/m2pp.c:  (ptc), (m2pp_getaligned),
          (m2pp_recordfield_alignment) New functions.
        * gm2/gm2-compiler/M2GCCDeclare.mod:  fixes to
        * DeclarePackedType.
        * gm2/gm2-compiler/P2SymBuild.mod:  fixes to
        * HandleRecordFieldPragmas.
        * gm2/gm2-compiler/SymbolTable.mod:  fixes to

this is an interim checkin.  But the good news is that one can now
declare packed record fields for types: subrange, enumerations and sets.
However as yet gm2 cannot access them..  this is being worked on at
present.  On Debian x86_64 there are no more regression test failures
than before these changes took place.  I get 18 failures (3 tests
failing x 6).  Two of which are because integer arithmetic range
checking has not been implemented.
