Re: [PATCH v4 2/3] parse-options: add cast to correct pointer type to OPT_SET_PTR

> Do not force users of OPT_SET_PTR to cast pointer to correct
> underlying pointer type by integrating cast into OPT_SET_PTR macro.
>
> Cast is required to prevent 'initialization makes integer from pointer
> without a cast' compiler warning.
