This should have been committed along with rev. 1.36 of Main.c (and
others) yesterday, but for some reason it got left out.

Change the way Main.main is run, so it now doesn't force the return
value.  Now 'main = return undefined' will run and exit successfully.

The change affects finalizers too - but since they have type IO (), it
won't do any harm not to evaluate the ().
