By default, GDB doesn't pass SIGINT to the process:

(gdb) info signal 2
Signal        Stop      Print   Pass to program Description
SIGINT        Yes       Yes     No              Interrupt

If you want it to do so, type:

(gdb) handle 2 pass

Assuming Cygwin has stty, if you type "stty -a" what is SIGINT (intr) bound
to?  Does it say ^C does anything?  If you want it to send SIGINT type:

stty intr ^C  (remember to use quoted-insert (^V) before typing ^C).
