The premise of Rob's ``solution'' is that *all* files have a '.'
somewhere.  This doesn't work, e.g., for s.Makefile -> Makefile. For that
to work, a ',' would have to operate as a SUFFIX delimiter, which it does
not do in ``standard'' make. There's no way to make make make Makefile
from Makefile,v using ony SUFFIX-based rules. An explicit dependency line
and rule would be required for each and every file.

P.S. Note that make will automatically do a get if there is an s.Makefile
(or s.makefile) and neither Makefile nor makefile exist.  In short, make and
SCCS are well integrated.
