When compiling with MLton, you should use mlprof.cm.  Note the line in
the Makefile for the mlprof (aka $(NAME)) target.

	$(MLTON) $(FLAGS) $(NAME).cm

So, you could also just do "make mlprof".

To type check with SML/NJ, do

	CM.make "sources.cm";

The basis structures are all packaged in the Pervasive structure, so,
e.g. Pervasive.TextIO should do the trick.
