According to Jim Meyering on 6/23/2008 2:12 AM:
| 83 ASSERT (old_sa.sa_flags == 0);
|
| And the value of old_sa.sa_flags is 0x4000000,
| which happens to be SA_RESTORER.
Ah. An extension flag, not defined by POSIX. In short, gnulib can't make
any assumptions about the state of bits outside of what POSIX requires.
So I'm checking in this; let me know if it fixes the problem.

Hmm. Should the open-safer module depend on open?

Revert use of sig-handler.h in sigprocmask.c.
* modules/sigprocmask (Files): Don't rely on sig-handler.h, since
it requires the existence of struct sigaction.
