/**
* GDK_WINDOWING_X11:
*
* The #GDK_WINDOWING_X11 macro is defined if the X11 backend
* is supported.
*
* Use this macro to guard code that is specific to the X11-backend.
* Since GDK may be configured with multiple backends, an additional
* runtime check for the used backend is recommended:
* </para>
* <example>
* <title>Backend-specific code</title>
* <programlisting>
* #ifdef GDK_WINDOWING_X11
* if (GDK_IS_X11_DISPLAY (display))
* {
* /&ast; make X11-specific calls here &ast;/
* }
* else
* #endif
* #ifdef GDK_WINDOWING_QUARTZ
* if (GDK_IS_QUARTZ_DISPLAY (display))
* {
* /&ast; make Quartz-specific calls here &ast/
* }
* else
* #endif
* g_error ("Unsupported GDK backend");
* </programlisting>
* </example>
