Can't compile any shader with the OpenGL ES 2 Emulator

Hi there!

I somehow managed to break the emulator, like it seems, since every shader I try to compile fails with this:

0(2) : error C0118: macros prefixed with 'GL_' are reserved

This happens with the samples provided by the SDK as well, and all my shaders run fine on my friends computer.

Since this does happen with the samples as well, you can be sure, that the problem isn't a makro prefixed with "GL_", because there isn't such a makro in the Cube-Sample, and neither in my code.

I'm on a NVidia GTX570, by the way.

Has anyone ever experienced something like this? Any help would be appreciated, I can't continue my project otherwise...
