 I am trying to build CEGUI 0.8.7 on Mac OS 10.8. The newest Xcode (version
 5.1.1) uses Clang 5.1. When I try to build CEGUI the GLM header file
 glm/simd/platform.h is included. This header file stops compiling and
 displays this error message stating that Clang 6 or higher is needed:

 "GLM requires Clang 3.4 / Apple Clang 6.0 or higher"

 I have the newest version of glm from MacPorts installed (version
 0.9.9.5).

 I think a simple solution to this problem is to downgrade glm on Mac OS
 10.8 and older.
