[GRASS-windows] Compiling grass7 on msys/mingw?

Thanks for the help. You were right on both counts. I added the new
Html.make and edited the grass.py line 208 to:
     os.execvp("g.parser.exe", [name] + argv)

That works too, the scripts compile perfectly now. Although I realize
that some work around will be needed to make it OS generic.

Any idea why I get the other error for r.mapcalc, r.univar,
raster3d/base and v.voronoi?

I am happy to test / keep posting errors for grass70 and grass64 as I
use grass in Windows Vista regularly. Let me know if there is anything
specific I should be testing/ looking for.
