Weird. I suppose the headers are wrong then:

$ grep kCGLPFABackingVolatile
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library//Frameworks/OpenGL.framework//Headers/CGLTypes.h
kCGLPFABackingVolatile OPENGL_ENUM_AVAILABLE(10_7)                    =
 77, /* back buffer contents are volatile after swap */

Anyway, the #define is harmless even when kCGLPFABackingVolatile enum is
declared. So I pushed it. Thanks

Jose
