Patches to improve Fortran support

This is great, we have a longstanding PR on this:

  gdb segfaults associated with FORTRAN (g77) array arguments

I can review this patch later this week (Wednesday or Thursday).
Someone else might be able to get to it before then.

Do you have a copyright assignment on file with the Free Software

Andrew C, do you think that this patch is big enough that an
