I'm doubt that: if the () were absent, the shell would cd to sources,
call make, and *never switch back* to the starting directory. For
a single command in the rule, that's OK, because the shell that
got called by make will exit, and you're back to make's working
directory. *But* if you call any other programs, that might
mess it all up.

Just forget about using any DOS programs: since this is for DJGPP, and
by now probably all DJGPP'ers are using GNU make, why not do it the GNU
way?

libraries: config.h
	$(MAKE) -C sources

Works absolutely perfect, at least with the recent (V2-based) make from
DJ.
