Missing proto for sigaction() in <sys/signal.h>

[Mumit Khan]

I don't have a POSIX spec handy, but I believe that sys/signal.h
should have the prototype for sigaction(). It's already defined
in winsup/signal.cc, so no harm done even if I'm wrong.

Here's a trivial patch for newlib/libc/include/sys/signal.h:

*** signal.h.~1	Tue Mar 25 22:32:25 1997
- --- signal.h	Tue Mar 25 22:36:57 1997
*************** struct sigaction 
*** 25,28 ****
- --- 25,30 ----
  #define sigemptyset(what)   (*(what) = 0)
  
+ int sigaction (int __sig, struct sigaction *__act,
+     struct sigaction *__oldact);
  int sigprocmask (int how, const sigset_t *a, sigset_t *b);
  #endif /* _STRICT_ANSI */
