[Mesa-dev] [PATCH mesa v2] glx: add GLXdispatchIndex sort check

[Eric Engestrom]

v2: make sure the list is in the order C's strcmp uses (Ilia)
    Ilia: I used LC_ALL instead of LANG, as it takes precedence
          (ie. LANG=C in this script would be overridden by
          LC_ALL=en_US in the environment).
