commit edf1c760 breaks compilation with gcc 5.1.0

Hello, commit 'edf1c760...' (configure: add support for C++11) breaks compilation of vlc with gcc 5.1.0 while gcc 4.9.2 compiles that commit and HEAD just fine.

I tested this of my Archlinux x86_64 boxes (one with gcc 4.9.2 and one with gcc 5.1.0).

P.S. I dug to this commit by help of 'git bisect'.

Some news: VLC compiles fine if I disable projectM support (--disable-projectm).
