Currently the ld64 on Darwin seems to create warnings of the form...
can't find atom for N_GSYM stabs i:G(0,2) in /var/tmp//cc6KtMzX.o
when compiling Fortran COMMON blocks at -m64 with the -g flag. These warnings
incorrectly cause about 38 apparent fortran testsuite failures on Darwin. This
problem can be suppressed until the issue causing the warnings (whose cause is
currently unknown) is addressed. The following patch (sorry about the unified
format) allows these warnings to be pruned and ignored during a -m64 make
check.

With this patch in place the fortran testsuite failures for -m64 are identical
to those for -m32 with three unexpected passes. This patch will help remove
the "noise" off of the Darwin -m64 test results.
