Yeah.  Try harder to upgrade!

The way to do complicated scripting in pre-python gdb is horrible:

1. Use set logging to write to a temporary file.
2. Run a gdb command that generates the output you need.
3. Use "shell" (and the scripting of your choice: sed, awk, perl...)
   to rewrite the temp file to a second temp file that is in
   gdb CLI syntax.
4. "source" the second temp file

Of course, you could hack gud-mode to do this automatically :-)
