Yes:

The one that comes with Xcode to build apps on ios (Iphone/Ipad)

i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658)

Same result when using Xcode and making a C project for OSX: "redefinition of
typedef is a C11 feature". And it seems that the apple compiler does not
support C11


I do not have the error with gcc that comes from macports:

I thought too so I did a quick search and I could not find one example from
GStreamer.

Apparently GstGLDisplay, GstGLWindow, GstGLShader, GstGLDownload etc ...


Also I forgot to add lot of files in my patch, so a new patch follows!
