4.2 Backport fix for PR libfortran/31196

I think you don't need Mark's approval. The gcc.gnu.org front page  
says "regression fixes & docs only", which IIRC this PR is (a  
regression wrt g77).

Furthermore, I haven't seen any news of a release since 2007-03-22  
(http://gcc.gnu.org/ml/gcc/2007-03/msg00865.html), which is more than  
3 weeks ago, so I guess things have slowed down.
