[M3devel] slight hudson/opencsw oddity

Our current separation of Hudson jobs for m3cc and cm3 will only work
if we start with m3cc _and_ the new cm3cg can be used by the _old_
cm3 front-end. If we expect more incompatible changes related to the
cm3-gcc interface, we should indeed consider a version mechanism there
at least to detect mismatches.
