Make variables and shell variables

[Andrew Hume]

the only way i know to communicate between two independently spawned
a.out's is the file system. thus, a simple solution might be

.c.o:	`cat CC` `cat CFLAGS` -c $goo (whatever goo is these days)

compiler1:
	echo compiler1 > CC; echo 'special flags' > CFLAGS
and so on.
depending on how correct you want things, you may want to have all the .o's
depend on CC and CFLAGS.
