    1.17 +// Test case code for checking legacy behaviour of graphics_openglesheaders
    1.18 +// The purpose of this source code is to throw an error during compilation
    1.19 +// if the contents of the #included header files has any symbol which is not
    1.20 +// part of the EGL 1.1 API specification even though later versions of EGL add new
    1.21 +// symbols to the namespace in a backwards-compatible way.

    1.23 +//
    1.24 +
    1.25 +// #define __OPENGLESHEADERS_LEGACY_EGL_1_1
    1.26 +// Such a setting would normally be made in an OEM-specific system-wide
