   including both overloadable operators (like `+') and

   non-overloadable operators (like the `?:' ternary operator).

/* The DEF_OPERATOR macro takes the following arguments:

   NAME

     The name of the operator, as a C string, but without the

     preceding `operator'.  This is the name that would be given in

     the source program.  For `operator +', for example, this would be

     `+'.

   CODE

     The tree_code for this operator.  For `operator +', for example,

     this would be PLUS_EXPR.  Because there are no tree codes for

     assignment operators, the same tree-codes are reused; i.e.,

     `operator +' will also have PLUS_EXPR as its CODE.

   MANGLING

     The mangling prefix for the operator, as a C string, and as

     mangled under the new ABI.  For `operator +', for example, this

     would be "pl".

   ARITY

     The arity of the operator, or -1 if any arity is allowed.  (As

     for `operator ()'.)  Postincrement and postdecrement operators

     are marked as binary.

   ASSN_P

     A boolean value.  If nonzero, this is an assignment operator.

   Before including this file, you should define DEF_OPERATOR

   to take these arguments.

   There is code (such as in grok_op_properties) that depends on the

   order the operators are presented in this file.  In particular,

   unary operators must precede binary operators.  */
