Fix for cygwin gdb hangs

Fix for cygwin gdb hangs

[Christopher Faylor]

Hello,
The cygwin32 port of gdb has an annoying habit of hanging hanging Windows
NT if the gdb 'kill' command is used or if an attempt is made to exit
gdb without allowing the debugged program to run to completion.
This patch should solve that problem.

-Chris Faylor

	Patch from cgf@bbc.com (Chris Faylor)
	* win32-nat.c (child_mourn_inferior): Make sure that child continues
	from EXIT_PROCESS_DEBUG or it could hang around forever.
	(child_kill_inferior): Respond to all debug events as the child
	is terminating or risk invoking a Windows NT bug which eventually
	hangs the whole system.

Thanks.  I've been annoyed by that problem for a while, but never
quite enough to figure out what was causing it.  I checked the patches
into the main sources.
