    test-includes: Add -ansi to the compile line to catch problems
    
    We support C89 files, but compile everything in the tree with C99 or
    newer. By compiling these -ansi, that will force C89 which doesn't
    understand inline. All our header files must use __inline instead of
    inline when they define inline functions.
