 * where ;
 * <SYMBOLIC_NAME> is a legal C identifer that will be used in the

 *
 * <ARGUMENT_COUNT> is an integer literal specifying the total number of

 *
 * <EXCEPTION_NAME> is an enum JSExnType value, defined in js/ErrorReport.h.
 *
 * <FORMAT_STRING> is a string literal, optionally containing sequences
 * {X} where X  is an integer representing the argument number that will
 * be replaced with a string value when the error is reported.
 *
 * e.g.
 *
 * MSG_DEF(JSMSG_NOT_A_SUBSPECIES, 2, JSEXN_TYPEERROR,
 *         "{0} is not a member of the {1} family")
 *
 * can be used:

 * JS_ReportErrorNumberASCII(JSMSG_NOT_A_SUBSPECIES, "Rhino", "Monkey");
