[Gm2] latest cvs changes (bug fix)

[Gaius Mulley]

Hi,

here are a few more bug fixes which have been applied to gm2.
These bug fixes allow align8.mod to pass the regression test.

  * gm2/gccgm2.c:  (gccgm2_BuildStartFieldVarient,
    gccgm2_BuildEndFieldVarient) New functions.
  * gm2/m2pp.c:  detect FIELD_DECL in m2pp_type.
  * gm2/gm2-compiler/M2GCCDeclare.mod:  use
    BuildStartFieldVarient rather than BuildStartVarient.
    Use BuildEndFieldVarient rather than BuildEndVarient.
    This fixes a number of regression test bugs including:
    testsuite/gm2/extensions/run/pass/align8.mod.
  * gm2/gm2-compiler/gccgm2.def:  define BuildStartFieldVarient
    and BuildEndFieldVarient.

regards,
Gaius
