    # Build note:
    #   We need to modify /usr/i686-w64-mingw32/include/GL/ directory because
    #   MinGW w64 bundles old OpenGL headers. Here are changes to build Cogl:
    #
    #   (1) Put the latest glext.h that can be downloaded from
    #       https://www.opengl.org/registry/api/GL/glext.h into
    #       /usr/share/mingw-w64/include/GL/ directory:
    #
    #         % wget https://www.opengl.org/registry/api/GL/glext.h
    #         % sudo install glext.h /usr/share/mingw-w64/include/GL/
    #
    #   (2) Add missing declarations and includes to
    #       /usr/share/mingw-w64/include/GL/gl.h:
    #
    #       Before:
    #         ...
    #         typedef double GLdouble;
    #         typedef double GLclampd;
    #         typedef void GLvoid;
    #
    #         #define GL_VERSION_1_1 1
    #         ...
    #
    #       After
    #         ...
    #         typedef double GLdouble;
    #         typedef double GLclampd;
    #         typedef void GLvoid;
    #
    #         typedef ptrdiff_t GLintptr;
    #         typedef ptrdiff_t GLsizeiptr;
    #         typedef char GLchar;
    #         #include <GL/glext.h>
    #
    #         #define GL_VERSION_1_1 1
