No excuse :-).  DODUMP hasn't existed for about 6 months.  Use dumpon(8).

Perhaps known bogus options should be checked for in a central source file:

#ifdef CHILD_MAX
#warning "bogus option CHILD_MAX, RTFM setrlimit(2), sh(1) (ulimit)"
#endif
#ifdef DODUMP
#warning "bogus option DODUMP, fix your configuration and RTFM dodump(8)"
#endif
