If this is OK along with no copyright assignment, I can submit a PR.
The copyright should probably extended to 2007. I think also than one 
should notify Alexandre Oliva.

I haven't any copyright assignment unless there is a global one with the
french CNRS (Centre National de la Recherche Scientifique), but if one is
required to replace g77 by gfortran we are really living in a sad world!

This part is trickier.  First I'll have to learn the basics of texi, since
I have never used it.  Second I am afraid to be writing challenged.  Third
I don't have much time to overcome these shortcomings.  

As a first shot, I think the header of "test_installed" with the proper
format will be enough.  In my opinion the most important point is the
visibility of the entry point, just to get the information that the script
exists.  My guess is that people interested by postinstall testing will be
able to run the script from its comments and, if I am wrong, feedback will
help to put the entry in better shape.  This entry point could probably be
inserted as a seventh item in

http://gcc.gnu.org/install/
