[CM] clm-2 OS X woes

[Michael Klingbeil]

Thanks for the config suggestion. In fact there were a bunch of other 
configuration problems that needed to be sorted out. The last version 
of clm-2 (June 30, 2004) expected that the working directory was set 
to the clm-2 directory so config.h was never getting built and then 
it was dumped into the wrong place.

Also *cflags* in all.lisp needed " -I" clm-directory and similar 
changes were needed in defins.lisp.

I noticed that most of these things made their way into clm-3 [ 
although I think line 160 in defins.lisp for clm-3 5-Aug still needs 
the following:

(defvar *cflags* (concatenate 'string " -I" clm-directory
	" -O2 -g"  ; the -O2 is needed!  strange errors from ACL if 
it's omitted

]

In any case since things have branched to clm-3 perhaps these clm-2 
fixes are less relevant. I thought I would send this to the list 
anyway in case people are still doing clm-2 stuff.
