// GTK2 stub for Zandronum's 3.2.1 Linux binary (zandronum3.2.1-linux-x86_64.tar.bz2)
// Compile to a "libgtk-x11-2.0.so.0" shared library file and make it visible to Zandronum.
// For AUR's zandronum 3.2.1-2, you can do this by:
// $ gcc zandronum-libgtk-x11-2.0-stub.c -shared -fPIC -o libgtk-x11-2.0.so.0
// $ sudo mv libgtk-x11-2.0.so.0 /usr/share/zandronum/lib

#include <stdio.h>
#include <stdlib.h>

// Zandronum calls this function on startup. Tell it GTK2 is not available.
