* \brief Workarounds for building with GLES2 and GLES3.
*
* When building shader_runner against GLESX and libpiglitutil_glesX, there
* are many macros and symbols that are not defined. This header defines such
* macros to have the same value found in <GL/gl*.h>, and defines such
* functions to print an error message and then report PIGLIT_SKIP, just as
* piglit-dispatch does for unsupported extension functions.
