I probably phrased this badly.  The trick with getting a patch through
quickly is to go over it repeatedly with a fine tooth comb until you've
removed everything that isn't directly related to the intended change.

There isn't a necessity for a long discussion however I think it is
reasonable for me to ask you to explaine the rationale behind the
introduction of a new directory.  Remember, you're putting in place
conventions that will last a very long time - it is important to get
them reasonably right first up.

If it were me doing this work, I would have broken it down into several
stages:

	o	create cp-abi.[hc]

		Here, the only thing
		anyone could possibly object
		to is the name :-)

	o	re-structure language
		directories

		I'd be seeking idea's from all
		the players (C, Pascal, O-C,
		et.al.)
