// for a little more background on the usage of these macros.

//                           in all builds.
// 
// To replace this system, just provide different macro definitions in your
// prefix header.  Remember, any implementation you provide *must* be thread
// safe since this could be called by anything in what ever situtation it has
// been placed in.
// 

// We only define the simple macros if nothing else has defined this.
