From 2c5616722ce57858a614fc53b7351c60d86c627c Mon Sep 17 00:00:00 2001
From: drochner <drochner@pkgsrc.org>
Date: Mon, 6 Oct 2003 11:14:14 +0000
Subject: Oops, need another #ifdef and a typecast to make this compile with
 old "struct sigaction" declarations. Also clean up bookkeeping whether the
 handler is already installed (which didn't work as intended because SIG_DFL
 is represented by a zero).
