	PR 433/tools
	* mips-stub.c: Patch from C. M. Heard <heard@pobox.com> described as:

	The purpose of the patch is to make the stub ignore all
	characters except '+' (ack) or '-' (nak) when it has transmitted a
	packet and expects an acknowledgment. Without the patch,
	putpacket() will retransmit each time it receives anything other
	than '+' when expecting an ack, and that, bitter experience has
	found, frequently results in the stub failing to sync up when
	initially attaching to gdb.

	I think that rtems users will notice significant improvement in
	the of the mips stub if this patch is incorporated in the
	distribution; certainly I did in my stand-aline environment. I
	should hasten to add that it is only an improvement and not a 100%
	cure for synchronization problems because '+' characters can (and
	do) during as message data, and it's still possible for these to
	be mistaken as acks. I have no idea how to fix that short of
	redesigning the gdb-remote protocol.
