From c55fae43c4e10e2779e4fb7d70d6f6e4a7645a63 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ren=C3=A9=20Scharfe?= Date: Sun, 21 Dec 2008 02:28:48 +0100 Subject: [PATCH] fast-import.c: stricter strtoul check, silence compiler warning Store the return value of strtoul() in order to avoid compiler warnings on Ubuntu 8.10. Also check errno after each call, which is the only way to notice an overflow without making ULONG_MAX an illegal date.
