Re: g++ 2.95.2 calculates wrong size for class

    Well I totaly missed the one virtual method which added the vtable entry
about 10 times, mostly since the windows compile of the project was
returning 8 (aparently the intel compiler was optimizing it out totaly since
it was never referenced in a virtual manner and was inlined completely).  I
hadn't compiled debug in windows in ages, since the code has been working
there over a week (and was delayed a week on the linux side due to a 3rd
party library needing some fixes).
