[MLton-commit] r7419

[Wesley Terpstra]

Another multiple target bug.

This says to build the two output files by executing the rule twice.
front-end/mlb.grm.sig front-end/mlb.grm.sml: front-end/mlb.grm
	$(MAKE) -C front-end mlb.grm.sig mlb.grm.sml

This describes a target-group rule that generates two files at once.
front-end/%.grm.sig front-end/%.grm.sml: front-end/%.grm
	$(MAKE) -C front-end $(<F).sig $(<F).sml

... though you'd think they behave the same since they look alike, they don't.
