[Gm2] Gm2-4.7.3: progress of some sort

[john o goyo]

I was finally able to download the combined tarball gcc+gm2 for 
gcc-4.7.3.  Configure ran to completion but gmake failed at libgm2.
In particular, there are many conditional compilations (HAVE_*) and
configure in libgm2 did not define a single one.  I defined all the
conditional flags and put them in a single header file, included in
all the C files in libgm2/libpim.  The build actually completed but
little of libgm2 was built.

So, some progress...
