Log message:
	Contrary to what was recommended in
	http://www.cs.unipr.it/pipermail/ppl-devel/2008-September/012736.html,
	returning from main is non-portable only to the most ancient C compilers.
	On the other hand, finding a suitable declaration for exit() is more
	problematic.  (Thanks to Ralf Wildenhues for pointing out that.)
