+Subject: [PATCH] xeglgears: Make EGL_KHR_image usage portable
+
+EGL extension functions don't have to be exported which means
+xeglgears was failing to link against implementations that
+support EGL_KHR_image but were not exporting its related functions.
+
+This has been fixed by using eglGetProcAddress to get a function
+pointer instead of using the functions prototype. This is portable.

+Subject: [PATCH 1/2] mesa-demos: Fix build when EGL_MESA_screen_surface
+ extension isn't present
+
+The EGL demos won't build against EGL implementations that don't support 
+the EGL_MESA_screen_surface extension. Fix this, in most cases, by 
+wrapping relevant bits of code in #ifdef EGL_MESA_screen_surface.
