As you know make traditionally reads (in order)

sys.mk                  found via MAKESYSPATH
[mM]akefile             typically in .CURDIR
.depend                 typically in .OBJDIR

.depend isn't a good name for something that would be checked into 
the SCM - Makefile.depend or Makefile.depend.* are reasonable choices
for that.  

Requiring that each [mM]akefile explicitly .-include something 
a/ is clunky compared to the above
b/ as joerg pointed out loses the special handling of stale dependencies
