Verified on x86_64-linux-gnu that no generated code changes at all.
A good follow-up cleanup here would be to replace the four magic values
used throughout the code (0, 1, -1, -2) with an enum.


Thanks,
Roland


	* nptl/descr.h (struct pthread): Change type of field setxid_futex
	to 'unsigned int'.
