Since when?  I've been doing 'gmake check-fortran' and
'gmake -j6 check-fortran' for more than 15 years.  There
was never an error.  This broke recently.

I just did a bootstrap of the 8-branch.  'gmake -j6 check-fortran'
completes without an error.  The last few line are

                === gfortran Summary ===

# of expected passes            6413
# of expected failures          18

Something is broken with trunk.  These do not occur on 
the 8-branch.
