+/* 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. */
