Person a:
    The best solution would be to have /* /* */ generate a warning.

Well, la-de-da.  When doing "multiple choice" #define's it is usually the
most portable way.  For example, from my news/mail gateway code:
    /* Where does the control file for talk.foo live?
     *	IN_ONEPLACE:	specified filename
     *	IN_SPOOLDIR:	/usr/spool/news/talk/foo/recnews.cmd
     *	IN_CMDDIR:	/usr/lib/news/.admin/talk.foo
     * Required, but you can set IN_ONEPLACE to /dev/null to disable it. */
    /*efine IN_ONEPLACE		"/dev/null"		/* .. */
    /*efine IN_SPOOLDIR		"/usr/spool/news"	/* .. */
    #define IN_CMDDIR		"/usr/lib/news/.admin"	/* .. */

Doesn't seem grotesque to me.  As moderator of comp.sources.unix I see
it all the time, and encourage it.
