From 90ff12a86073e27c9f423a255a4da4314c28936d Mon Sep 17 00:00:00 2001 From: Michael Wookey Date: Sat, 30 Jan 2010 09:38:19 +1100 Subject: [PATCH] run-command.c: fix build warnings on Ubuntu Building git on Ubuntu 9.10 warns that the return value of write(2) isn't checked. These warnings were introduced in commits: 2b541bf8 ("start_command: detect execvp failures early") a5487ddf ("start_command: report child process setup errors to the parent's stderr") GCC details: $ gcc --version gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1 Silence the warnings by reading (but not making use of) the return value of write(2).
