From cea13a8d685802389fad5b1ffce3af38175a8a01 Mon Sep 17 00:00:00 2001 From: Giuseppe Bilotta Date: Mon, 28 Mar 2011 09:39:59 +0200 Subject: [PATCH] Improve test for pthreads flag When compiling with CC=clang using Clang 1.1 as shipped by Debian unstable (package version 2.7-3), the -mt flag is sufficient to compile during the `configure` test. However, building git would then fail at link time complaining about missing symbols such as `pthread_key_create' and `pthread_create'. Work around this issue by adding pthread key creation to the pthreads configure test source.
