Fix a warning about ‘sincos’ in examples/cogl-gles2-gears
‘sincos’ is a GNU extension. cogl-gles2-gears was using it without defining _GNU_SOURCE so it was generating some annoying warnings. This patch fixes it by making the example include config.h which will end up defining _GNU_SOURCE. In addition this patch adds a configure check for the function and provides a fallback if it's not available. https://bugzilla.gnome.org/show_bug.cgi?id=697330 Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit eb5c92952e1882c95cfd6debc69a2c9efff096b9)
