? The standard MAKE program understands SCCS and not RCS.  This one limitation
? is solved by intelligent setup of the makefile dependencies.

Try

.DEFAULT:
	co $@

Of course, then you must explicitly list that every .o file depends on the
corresponding .c file.

Another gambit if you do not use a separate RCS directory and do not
keep sources checked out is:

.SUFFIXES: .c,v

.c,v.o:
	co $*.c
	$(CC) $(CFLAGS) -c $*.c
	rm $*.c

Apologys if I screwed up, I just typed this off the top of my head.

It is rumored that some people (ok, I give, U of Md. among others) have
hacked make to understand RCS, altho to what level , I don't know.
Maybe someone with initials ACT will clear this up. :-)

Finally, there is GNU make, which recognizes prefixes as well as suffixes,
in a totally new (gnu?) way. I have it but haven't used it yet.
