Hi Sam, and thanks for the report.

I'll try to look at one failure at the time ...

So far, so good ...

What, gfortran is not the GNU fortran compiler?  This looks fishy...

Hmm... this seems like a bug in your Fortran compiler.

By googling I found this:
 <http://130.237.222.241/list-archives/gmp-discuss/2010-November/004365.html>
with this answer:
 <http://130.237.222.241/list-archives/gmp-discuss/2010-November/004366.html>

Could it be related to the failure above?  More importantly, could you
confirm that failure is indeed due (as I suspect) to a bug in your
compiler, and not to a bug in automake or in its testsuite?

Thanks,
  Stefano
