According to the <u>OpenGL-2.1-Spec</u> the prototype for glStencilFuncSeparate should be (chapter 4.1.5, page 205):

Code :
glStencilFuncSeparate(GLenum face, GLenum func, GLint, GLuint);

<u>gl.psec</u> however defines something like:

Code :
glStencilFuncSeparate(StencilFunc frontFunc, StencilFunc backFunc, GLint, GLuint);

which is an alias to glStencilFuncSeparateATI() which should be wrong.
