Continuing.

<ctrl-c> => nothing happens
<window-resize> => thread is stopped.

[Thread 559480756.559480756] #1 stopped.


A Ctrl-C or (ctrl-break) at this point should suspend the thread again. The
ctrl-c is not handled correctly by GDB.
In cygwin 1.7 the Ctrl-C is handled correctly after a *window*resize*. 

See attached strace done on cygwin 1.7. 
(output taken after the 'continue' has been issued. There are two parts: 1 part
is output after ctrl-c , part two is what happened after the window resize.)
