Hi Devang,

I'll review such a patch.

Obviously you can't commit a patch which will break GDB for those who
use stabs.  However, what you can do is add the changes conditional on
a command-line option.  The option can be on for Darwin and off for
everyone else by default.

In addition, it would be good if you could:
- Report a bug against FSF GDB for the cases which aren't handled properly
- maybe even provide the patch against Apple GDB which fixed it, since
  it might help anyone who looks at the bug.
