    CTestCustom: Suppress scan-build warning in libuv
    
    Clang scan-build warns in some expansions of RB_GENERATE_STATIC
    that it has a "Dereference of null pointer".  Simply suppress it
    since this is third-party code anyway.

    libuv: Simplify variable initializations to satisfy Clang scan-build
    
    The Clang scan-build tool warns about assignments whose values are never
    used, so initialize local variables at declaration instead.
