Writing portable Makefiles usually always involves something that will
always be "dirty" to some/most. I still have makefiles lying around in 
our projects that were portable between Unix and VMS, and talk about 
dirty!

Make is a powerful tool, but the downside is that it's quite low-level 
and has been showing its age for a while now. Unfortunately, the general
purpose and cross-platform alternatives just haven't caught on and have 
remained in the dark arena called "research tools".

How about letting make saving you some error-prone typing:

   goal$(EXEEXT): goal.c
                  $(CC) -o $@ goal.c
                  cp $@ anothergoal$(EXEEXT)
                  mv $@ yet.another.goal

I prefer, and use, the former.
