// This macro applies an argument macro to all OopClosures for which we

//   "f(closureType, non_virtual)"
// where "closureType" is the name of the particular subclass of ExtendedOopClosure,
// and "non_virtual" will be the string "_nv" if the closure type should
// have its "do_oop" method invoked non-virtually, or else the
// string "_v".  ("ExtendedOopClosure" itself will be the only class in the latter
// category.)

// This is split into several because of a Visual C++ 6.0 compiler bug
// where very long macros cause the compiler to crash
