No, because the linker ALWAYS receives ALL the objects files. The rule 
typically looks like this

foo.exe: $(OBJS)
         $(LINK) $^ -o $@

If you would do the same with the compiler, you would *always* compile 
*all* source files. Instead, compiler rules typically look something 
like this:

.c.h:
	$(CC) -c $< -o $@

This will invoke "cl -c foo.c -o foo.o", once for each source file which 
is out of date. I cannot see how the /MP option allows cl to 
parallellize over all the source files it should compile.

This is getting too off-topic for CDT, so I'll stop here. Sorry if I'm 
not able to make myself clear.
