Jim just explained this, but it may not have been clear: that is the
wrong way to forward the signal.  If you are running GDB on a
pseudo-tty, you need to forward the job control signal to that TTY, not
to the GDB process itself.

I don't really know how to do that.  Is it by setting BRKING in
termios?  There's something about TIOCSIGNAL too.  Lots of code for
this in emacs.
