** Implementation notes (a few).
*
*
* The intent is that routines that return mcxstatus can define their own
* values, so one must check the interface of a given routine as to what kind
* of symbolic values it may return.
*
* For example, the opt library defines MCX_OPT_OK, MCX_OPT_NOARG, and
* MCX_OPT_UNKNOWN.
*
* The intent is also that the OK value is always defined as zero -- it's
* not the zero that counts but the fact that all OK values (e.g. STATUS_OK,
* MCX_OPT_OK etc) are equal. One should be able to count on this.
* If multiple ok values are possible, use one of mcxenum, mcxbits, mcxmode.
