This patch fixes "../sysdeps/nptl/pthread.h:670:26: warning: initialization discards 'volatile' qualifier from pointer target type" arising when building nptl/tst-cancel-self-cancelstate.c. The problem is passing a volatile int * to a macro expecting void *; the patch adds an explicit cast. Tested for x86_64. * nptl/tst-cancel-self-cancelstate.c (do_test): Cast argument of pthread_cleanup_push to void *.
