There is really only one issue - when sis is connected to gdb, a running
program cannot be interrupted by pressing ctrl-C in gdb. The program can
be stopped by pressing ctrl-C in the simulator window instead, which is
maybe a sufficient workaround..? I will start by letting sis print a
warning for this if gdb mode is entered under cygwin. If there are (too)
many complaints, I will look at it again...
