Alway typing "make -r", is probably inconvenient.

A portable way to use some GNU Make syntax is to add a
GNUmakefile near your Makefile{,.in,.am}.  This GNUmakefile
would look as follows :
  
include Makefile
% : RCS/%,v
% : %,v

This way GNU Make will uses these rules in addition to the
ordinary Makefile.  But Automake and other Make implementation
never see them.

BTW, escaping # is not portable.  Here setting 
  CO = :
would be safer.
