From: Giuseppe Bilotta Date: Mon, 28 Mar 2011 07:39:59 GMT Subject: [PATCH] Improve test for pthreads flag Message-ID: <1301297999-30130-1-git-send-email-giuseppe.bilotta@gmail.com> 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.
