can anyone explain why the following makefile works:

.c%v.c:; co $@
 
sccommon.h: rcs\sccommon.h%v
	co sccommon.h

(heres the trace)
*** Read c:\develop\bin\unix\make.ini ***
*** Done c:\develop\bin\unix\make.ini ***
*** Read Makefile ***
*** Done Makefile ***
*** Tracing NDMAKE ***
sccommon.h                          Doesn't exist
    rcs\sccommon.h%v                +
    ^----------- is newer than sccommon.h

==========================================================================
But this one doesn't:

co sccommon.h
sccommon.h                          
	.h%v.h:; co $@
 
sccommon.h: rcs\sccommon.h%v
*** Read c:\develop\bin\unix\make.ini ***
*** Done c:\develop\bin\unix\make.ini ***
*** Read Makefile ***
*** Done Makefile ***
*** Tracing NDMAKE ***
sccommon.h                          Doesn't exist
    rcs\sccommon.h%v                +
    ^----------- is newer than sccommon.h
