 // Description:

 // Test case code for checking current behaviour of graphics_openglesheaders

 // The purpose of this source code is to thrown an error during compilation

 // if the GLES/egl.h header does not re-direct to the system-wide EGL/egl.h

 // The use of GLES/egl.h is a legacy, and kept to ease the transition of

 // applications to using EGL/egl.h instead.

 // This code must be compiled without the legacy setting

 // __OPENGLESHEADERS_LEGACY_EGL_1_1 to ensure that GLES/egl.h re-directs

 // to the system-wide EGL/egl.h

 // 

 //
