Verified on i686-linux-gnu that no generated code changes nontrivially.

Thanks,
Roland


	* resolv/gai_misc.h (struct waitlist): Change type of field
	counterp to 'volatile unsigned int *'.
	* sysdeps/nptl/gai_misc.h (GAI_MISC_WAIT): Use unsigned types for
	FUTEXADDR and OLDVAL.
	* resolv/getaddrinfo_a.c (getaddrinfo_a):
	Give local variable TOTAL type 'volatile unsigned int'.
	(struct async_waitlist): Change type of field counter to 'unsigned int'.
	* resolv/gai_suspend.c (gai_suspend):
	Give local variable CNTR type 'unsigned int'.
