When checking if a string is prefixed by a drive letter (e.g. "C:") we verify this by inspecting the first and second character of the string. Coverity thinks this is a defect as we do not check the string's length first, but in fact we only check the second character if the first character is part of the alphabet, that is it cannot be '\0'. Fix this by overriding the macro and explicitly checking the string's length.
