Thanks, I see.

Your patch is ok.

It is interesting that I have never run across this particular failure
before.  This style of dependency tracking has been in use for a long
time...

I think the underlying problem is a bug in gcc.  I think -MP ought to
emit a dummy target for the primary source file as well.  I made a
note to fix this in libcpp.
