From 3ab4b632a068728516bea29831f7b24b73faa5a1 Mon Sep 17 00:00:00 2001 From: Austin Foxley Date: Sun, 20 Sep 2009 16:33:38 -0700 Subject: [PATCH] Add a config option for gcc tls support, rather than disabling it blindly Defaulted to yes, but blocked it from gcc 4.4.x since the disable was originally added because of problems with its c++ support reportedly.
