In the Unix Programmer's Manual (yes, it's RTFM time again, DK is too good
of a programmer to mess this one up) it notes under Make(1):

	"Commands that are directly executed by the shell, notably *cd(1)*,
	are ineffectual across newlines in *make*."

In other words, try this on the "cd smodel" line in your makefile: 

        cd smodel; cd

you should get "c:\tmp\smodel" back.
