+__OPENGLESHEADERS_LEGACY_EGL_1_1
+
+The purpose of this define is to allow the staged migration to
+EGL 1.3 from EGL 1.1 taken from the perspective of OpenGL ES 1.X
+
+If __OPENGLESHEADERS_LEGACY_EGL_1_1 is defined, then GLES/egl.h and
+GLES/egltypes.h will only provide the EGL 1.1 API; in particular no
+symbols from a later version of EGL will be seen at a source code level.
+This is considered to be legacy behaviour.  If
+__OPENGLESHEADERS_LEGACY_EGL_1_1 is not defined, the GLES/egl.h
+and GLES/egltypes.h header files will re-direct to the system-wide
+EGL/egl.h. and EGL/egltypes.h respectively.
+
+The use of GLES/egl.h or GLES/egltypes.h by applications is considered
+legacy behaviour because applications should instead use EGL/egl.h
+or EGL/egltypes.h respectively.
+
+When this legacy behaviour is desired, the define should be placed in an
+OEM-specific system-wide .hrh file.  Symbian product configurations
+never set this legacy behaviour.
