Make did auto-detect it somehow, but I also spotted it on Friday and added
it to the all requriements, but this is a better option. I am in the process
of doing a final check on attempt #3.

I now do anfter some more investigating, but I still don't know the
mechanism. This clean is called for each of the directories under the src
root. As gpp.opt is in the src root it does not get deleted.

I have added the following line to the src\makefile which causes the gpp.opt
to be deleted.

	$(MAKE) -f makempty clean
+	./misc.exe rm gpp.opt
	./misc.exe rm makemake.exe copyrite.exe misc.exe 

I will post an attempt #3 after re-building and checking everything after at
least 3 LIBC builds and clean cycles.

Regards,
Andrew
