	It sure would help if you read psd:12 from your 4.4 manual set if
	your going to do much more with Make.  On page 12-7 you will see
	#undef variable described.

	Note that our make uses .undef, and I have tested it, and it works.

Why do we use . instead of #?  I've installed pmake on my system,
but it's not a straight drop-in replacement for make due to this and
other differences.
