[comp.unix.wizards] nontemporal relationships in make

andrew@alice.UUCP (10/27/87)

I am looking for any reasonable or plausible examples of where
you would like to say (within make) that file a is `out of date''
with respect to file b on some other basis than ``is more recently modified
than''. one example might be 'thing.o depends on lines from goo.h
containing the RE (Thing|allthings)'.
