That -should- be fine.  I'm not terribly comfortable with it, though;
even given a sufficiently broken filesystem GCC should not loop
forever.  This also could backfire if something else creates a tempfile
with the same name - I suppose that's ignorable, though, since it's
vanishingly unlikely.

I'd really rather you create the tempfile on VMS in such a way that
multiple versions are not created.  Is that impractical?
