This breaks on ia64 because uc_sigmask does not have the correct type there:

tst-setcontext4.c: In function ‘do_test’:
tst-setcontext4.c:202:20: error: passing argument 1 of ‘sigismember’ 
from incompatible pointer type [-Werror=incompatible-pointer-types]
    if (sigismember (&oldctx.uc_sigmask, SIGUSR2) != 1)
In file included from ../include/signal.h:2,
                  from tst-setcontext4.c:23:
../signal/signal.h:208:41: note: expected ‘const sigset_t *’ {aka ‘const 
struct <anonymous> *’} but argument is of type ‘long unsigned int *’
  extern int sigismember (const sigset_t *__set, int __signo)
                          ~~~~~~~~~~~~~~~~^~~~~

I don't have a quick solution for this.  How important is this part of 
the test?

Thanks,
Florian
