In older versions of GDK, the constants were lacking the 'KEY_' part,
so it would have just been  GDK_Pause.

In GTK-VNC I worked around this by adding this kind of thing to our
source

  #ifndef GDK_Return
  #define GDK_Return GDK_KEY_Return
  #endif

Since there was a fairly small set of key constants that we needed to
care about.
