sigaction & 2.1.71

[Steven N. Hirsch]

All,

A recent change in the definition of struct sigaction and sigset_t has
broken almost every application I've built under > 2.1.69 or so. 

I've been forced to do something like this (one of at least a half-dozen
such patches required to build Midnight Commander):

*** tcputil.c.orig	Fri Oct  3 12:47:12 1997
--- tcputil.c	Sat Dec  6 11:42:48 1997
***************
*** 252,264 ****
  
  void tcp_init (void)
  {
!     struct sigaction sa;
      
      got_sigpipe = 0;
      sa.sa_handler = sig_pipe;
      sa.sa_flags = 0;
      sigemptyset (&sa.sa_mask);
!     sigaction (SIGPIPE, &sa, NULL);
  }
  
  int get_remote_port (struct sockaddr_in *sin, int *version)
--- 252,264 ----
  
  void tcp_init (void)
  {
!     struct old_sigaction sa;
      
      got_sigpipe = 0;
      sa.sa_handler = sig_pipe;
      sa.sa_flags = 0;
      sigemptyset (&sa.sa_mask);
!     sigaction (SIGPIPE, (struct sigaction *)&sa, NULL);
  }
  
  int get_remote_port (struct sockaddr_in *sin, int *version)

I am using the "traditional" libc, libc.so.5.4.33 to be precise.  Is there
something else that should be defined to properly revert to the older
behavior from the kernel headers?
