compile opencv3 alpha

edit

I've tried compiling the master branch from github and also the alpha that is downloadable from the OpenCV website. On both I get this error.

C:\opencv\opencv3\opencv\modules\core\src\system.cpp: In function 'BOOL cv::DllMain(HINSTANCE, DWORD, 
LPVOID)':

I didn't add any extra features other then openCL, building the examples, and adding QT. I am on Windows.

Thanks for your help.
