[Gm2] compiler options

[SiTex Graphics]

Hi Gaius,

1.  What compiler options are enabled by default (if any)?  (e.g.
-fcheckall etc)

2.  With the April 13 CVS, gm2 doesn't seem to recognize any of

-fno-nil
-fno-wholediv
-fno-index
-fno-range

3.  gm2 does recognize -fcheckall, but the linker returns a bunch of errors:
