I've recently cloned the latest revision in the repository (2013) and when I try to compile the addons I keep getting these errors inside the angelscript.h header:

I've tried MinGW 4.8.3 and 4.9.1 with -std=c++11 enabled and with Code::Blocks as the IDE. The main AngelScript project compiles successfully but the addons project fails to compile with that error. It's probably a configuration error on my part but just to be sure I don't pull my hair for nothing.
