Description of problem: I use 2.6.38.8-desktop-9.mga as kernel. As I run the ./configure command I get this message:

configure: error: support for required C++11 features incomplete

Version-Release number of selected component (if applicable): 4.5.2

How reproducible: Everytime I run ./configure

Steps to Reproduce:
1. Open a terminal.
2. Install requirements mentioned here: http://www.bunkus.org/videotools/mkvtoolnix/source.html
3. Now clone the git by typing as normal user: git clone git://github.com/mbunkus/mkvtoolnix.git
4. Type ./autogen.sh
5. Type ./configure
6. Voila! Can't finish the build due to to old gcc-version.
