new gfortran failures on darwin8

[Jack Howarth]

   Does anyone know why we are seeing all of these new fortran
testsuite failures for powerpc-apple-darwin8? Specifically from
http://gcc.gnu.org/ml/gcc-testresults/2007-06/msg01153.html we see
gfortran.dg/error_format.f90, gfortran.dg/open_status_3.f90,
gfortran.dg/read_comma.f, gfortran.dg/runtime_warning_1.f90 and
gfortran.dg/write_check.f90 failing across the board.
