dumpbin-osmesa-git-gallium

The osmesa.dll (gallium) build with scons on windows is missing a lot of
symbols. It seems that only the OpenGL<2.0 symbols are contained in the dll.

dumpbin /EXPORTS mesa-git\build\windows-x86\gallium\targets\osmesa\osmesa.dll

in total there are 336 gl* symbols. E.g. glClear or glVertex3d. However, 
glCreateProgram or glCreateShader is missing.

The classic osmesa.dll (swrast) contain many more symbols:
dumpbin /EXPORTS mesa-10.5.9\build\windows-x86\mesa\drivers\osmesa\osmesa.dll

in total there are 1436 gl* symbols. For example, it contains glCreateProgram,
glCreateProgramObjectARB, glCreateShader, glCreateShaderObjectARB,
glCreateShaderProgramEXT and glCreateTextures.

I'v attached the dumpbin output of both dll's
