* 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'.
* sysdeps/pthread/aio_misc.h (struct waitlist): Change type of field
counterp to 'volatile unsigned int *'.
* sysdeps/pthread/aio_suspend.c [DONT_NEED_AIO_MISC_COND]
