My problem seems to be the version.h rule.  If I move it to subdir.mak 
or common.mak then if I am in a subdirectory everything is fine and I 
get the dll with the resource in it and life is great.  However if I 
start make from the root directory I get a bunch of "common.mak:11: 
warning: ignoring old commands for target `version.h'", and eventually 
the make fails.  I think the rule for version.h needs to not be in 
Makefile so it works when building in a subdirectory but I'm not sure 
where to put it.  Any help?
