Re: bash fails to compile on systems with select() but not pselect()

[Larkin Nickle]

Line 145 also contains `sigprocmask (SIG_BLOCK, &set, &oset);` under 
`#elif defined HAVE_SELECT` even though `set` and `oset` aren't declared 
unless we have HAVE_PSELECT.

#if defined (HAVE_PSELECT)
      /* XXX - use pselect(2) to block SIGCHLD atomically */
      result = pselect (fd + 1, &readfds, (fd_set *)NULL, &exceptfds, 
(struct ti
mespec *)NULL, &set);
#elif defined (HAVE_SELECT)
      sigprocmask (SIG_BLOCK, &set, &oset);
      result = select (fd + 1, &readfds, (fd_set *)NULL, &exceptfds, 
(struct tim
eval *)NULL);
      sigprocmask (SIG_BLOCK, &oset, (sigset_t *)NULL);
#endif
