// Description:

// Test case code for checking legacy behaviour of graphics_openglesheaders

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

// if the contents of the #included header files has any symbol which is not

// part of the EGL 1.1 API specification even though later versions of EGL add new

// symbols to the namespace in a backwards-compatible way.

// This file must be compiled with the legacy setting

//

// #define __OPENGLESHEADERS_LEGACY_EGL_1_1

// Such a setting would normally be made in an OEM-specific system-wide

// included .hrh file.
