The method dispatching is different when you run the program from Think C
that it is when you build an application.  When you run from Think C it
does not appear to optimize method dispatching.  I noticed this because I
wanted to see how much overhead was involved in OO stuff in Think C, so
I wrote a test program and single stepped it with TMON.  Everything wemt
through the method dispatcher.  I then build the application and single
stepped.  Now many things did not go through the method dispatcher.  Instead
they jsr'ed to a jmp to the method.
