My first thought is that the OpenGL header file you're including doesn't support the GL_EXT_bgra extension. See this webpage for some more details. It would be interesting to know what OpenGL extensions are not supported when compiling against a MinGW GL/gl.h http://www.opengl.org/resources/features/OGLextensions/ I believe you could work around this with a software patch by swapping the blue and red channels on the entire buffer. -- Philip Lowman
