No, we use -Wno-uninitialized because of cases where it is obvious to
humans but not to gcc that a variable is initialized, such as:

    if (foo != NULL)
        bar = baz(foo);
    /* some code that doesn't change foo */
    if (foo != NULL)
        printf("%d\n", bar);

If you remove the code between the two ifs, gcc will coalesce them and
realize nothing fishy is going on (unless you compile with -O0).
