This is also true of SunOS 3.[45].

Try this one (curtesy r$):
Create a file named "markfile" that has only RCS info and check it in
	% cat >markfile
	$Header:$
	$Log:$
	% ci markfile
now, with the sysV-derived MAKE, you'll automatically get a file that has
	static char _sccsid[] = "$Header: markfile r1.3, 10/10/89 ...";
as its only line, which you can compile and do an "ident" on to see the
revision.
