  24 Since libX11 has not broken backwards binary compatibility since libX11.so.4,
  25 Solaris still ships it as libX11.so.4, instead of forcing applications to
  26 recompile against libX11.so.6.
  27
  28 We also apply our linker mapfile to set library versions for the public API
  29 and to hide the private APIs.
  30
  31 Lastly, we record libXext.so.0 as a required dependency, even though it's not
  32 directly required, to avoid breaking binaries such as the Java 1.1 runtime that
  33 assumed libX11.so.6 would always load it (Sun bug 6192234, Oracle bug 15235619).
  34
  35 For OpenIndiana we keep the separate mapfile for 64-bit builds
