macros/726: Internal GDB errors with current GDB snapshots and -gdwarf2-3

[Michael Elizabeth Chastain]

I think it's good to send the patch to gdb-patches as usual,
and then mail to gdb-gnats with a URL that points to the patch.
That means you have to for the patch to show up in the gdb-patches
archive, but that takes just a few seconds.
