So, what emits ``-Xcompiler -M'' stuff anyway?  Even still, with
a little thought it should be possible to avoid all that complexity.
When intertwined with the logic for handling the four-state
output file state, it becomes quite indecipherable.  But, now that
I know it is used to glue options onto command lines, it is at
least vaguely comprehensible. .... I'll have to think some more...
Minimally, I'll add some comments to the code.  :-)
