[Gm2] latest cvs changes

[Gaius Mulley]

Hi,

finally I've tracked down the off by one bug in the constructing a
constant array.  Here are the change log entries and also a bug fix to
dtoa.  Now the realstr regression test builds correctly and exposes
some real -> string conversion errors.

        * gm2/gccgm2.c:  copy result of TREE_CODE into a variable
          to aid debugging.
        * gm2/m2pp.c:  m2pp_constructor (new function).  Add
          INIT_EXPR as a pseudoname for MODIFY_EXPR.
        * gm2/gm2-compiler/M2ALU.mod:  fixed off by one bug when
          constructing array constants.
        * gm2/gm2-libs-ch/dtoa.c:  add '0' to the end of a copied
          string of significant digits.

I now see the following regression test results on x86_64

# of expected passes            7626
# of unexpected failures        60
# of unresolved testcases       30

regards,
Gaius
