/* The following structure is used when comparing various alternatives
   for overloading.  The unsigned quantity `strikes.i' is used
   for fast comparison of two possibilities.  This number is an
   aggregate of four constituents:

     EVIL: if this is non-zero, then the candidate should not be considered
     USER: if this is non-zero, then a user-defined type conversion is needed
     B_OR_D: if this is non-zero, then use a base pointer instead of the
             type of the pointer we started with.
     EASY: if this is non-zero, then we have a builtin conversion
           (such as int to long, int to float, etc) to do.

   If two candidates require user-defined type conversions, and the
   type conversions are not identical, then an ambiguity error
   is reported.

   If two candidates agree on user-defined type conversions,
   and one uses pointers of strictly higher type (derived where
   another uses base), then that alternative is silently chosen.

   If two candidates have a non-monotonic derived/base pointer
   relationship, and/or a non-monotonic easy conversion relationship,
   then a warning is emitted to show which paths are possible, and
   which one is being chosen.

   For example:

   int i;
   double x;

   overload f;
   int f (int, int);
   double f (double, double);

   f (i, x);	// draws a warning

   struct B
     f (int);
   } *bb;
   struct D : B
     f (double);
   } *dd;

   dd->f (x);	// exact match
   dd->f (i);	// draws warning

   Note that this technique really only works for 255 arguments.  Perhaps
   this is not enough.  */
