From b05a4e176a6e917b973a38a62e36e5aef5f938d5 Mon Sep 17 00:00:00 2001 From: millert <> Date: Thu, 30 Oct 2014 20:43:35 +0000 Subject: [PATCH] Don't mention old systems where realloc(NULL, n) didn't work as we don't want to give people the idea that this is non-portable (it has been present since C89).
