Description Ighighi 2006-10-01 21:58:45 AEST

If there's a reason at all to ship openbsd-compat/sigact.c these days, then a better support is needed for sigaction() and friends on non-POSIX systems.  There are NULL dereferences that shouldn't be there...
A summary of changes:
  + No NULL dereferences.
  + Added sigfillset()
  + Return -1 with errno set to EINVAL for corner cases.
