From 7ed20e1ad521b5f5df61bf6559ae60738e393741 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sun, 1 May 2005 08:59:14 -0700 Subject: [PATCH] convert that currently tests _NSIG directly to use valid_signal() Convert most of the current code that uses _NSIG directly to instead use valid_signal(). This avoids gcc -W warnings and off-by-one errors.
