It's Trisquel, the machine is fencepost.gnu.org. I think this is some
variety of Ubuntu, but I don't know enough about genealogy of Linux
distributions to tell. In any case, GDB 7.3 on that system was built
by me, it's not something that came with the OS.

It's XP SP3. Do you mean you don't get "(gdb)" after typing "end" on
Windows as well?

Perhaps turn on gdb-enable-debug, and see what you get in the
gdb-debug-log variable.

What if you run GDB from the shell, but using the -i=mi switch, and
set interactive-mode off? do you see the problem then?

It does, if you invoke "M-x gud-gdb RET". Another work-around, I
guess. But I still would like to find out why it doesn't work for you
with -i=mi?
