Thanks, Tino.

I've finally managed to get gdb to work by executing the following two
instructions at the gdb command prompt:

(gdb) cd ~/emacs
(gdb) file src/bootstrap-emacs

However, your suggestion to execute the following from the terminal, didn't
work:

> emacs ~/emacs/src

Is there a way to configure gdb to use the above settings (cd and file)
automatically?
