Thomas:

The question here applies to only the output of the SGI compiler's
automatic dependency generation, and perhaps other compilers that
use the same scheme(?).  If we had source for the SGI preprocessor
we could find out for certain, but I doubt that '::' will appear
anywhere in its output.
  I have attached a patch, made with the suggestions by Hari.
Unfortunately it wasn't made with cvs as I'm currently
in the midst of an outage. :(
