Re: Darwin -m64 results

     I don't believe that this warning with "-O3 -m64 -g" is
due to the fortran compiler optimizing away the storage.
If I compile...

      program test
      integer i,j
      common i
      do j = 1,100
      end do 

I still see the warning "can't find atom for N_GSYM stabs i:G(0,3)"
and I would be surprised if the storage for "i" was being optimized
away. I did one other test using the test case of...

      program test
      integer i
      common i

...with and without the common statement at both -m32 and -m64.
The resulting lines in assign.s introduced by the use of
the common section are identical in both -m32 and -m64 compiles...

...however only the ld64 linker issues the "can't find atom for N_GSYM stabs i:G(0,3)"
complaint. I think this suggests a bug in ld64, no?
