+ (suspend_one_thread): New.
+ (fake_breakpoint_event): New.
+ (get_child_debug_event): Change return type to int. Check here if
+ gdb sent an interrupt request. If a soft interrupt was requested,
+ fake a breakpoint event. Return 0 if there is no event to handle,
+ and 1 otherwise.
+ (win32_wait): Don't check here if gdb sent an interrupt request.
+ Ensure there is a valid event to handle.
+ (win32_request_interrupt): Add soft interruption method as last
+ resort.
