In os_dirent_get_typename() we are checking that type falls within the known values of the enum os_dirent_t. With clang-3.8 testing this value as being >= 0 results in a warning as it will always be true. This assumes of course that we are only given valid data. Given that we want to sanity check the input, we change this to check that it falls within the range of the first to the last entry in the given enum.
