// 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

//
