s4 should be locksurface2 according to JM's spreadsheet, and the spec indicates 2 is a clarification of 1, so we can't offer both

// 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.
//
