Currently there is nobody really actively working on the C++ gdb support, so I
think everybody will be happy if you try to improve it :-)
Since it doesn't support the machine interface, it isn't of much use for me
without some hacks. If debugging over the serial line gdb output and
applicatio output come intermixed and kdevelop considered the application
output as gdb termination message :-/
I think the machine interface would help against this.
