Destructors in C++ need not be called explicitly. The destructor for a class whether one has defined it or not gets called automatically and all objects associated with the class gets destroyed in the order of descending appearance in the class.

Well, the static variable should not be accessed from outside the file in hich it is defined. That's how static is defined.The intended purpose of static is to make the variable "invisible" to other programs.Hence you must use extern if you want to access it across files.Cheers,Kalayama

I believe that you may be able to override main (I haven't actually tried though..). I don't see why you'd get any linker errors if you re-def the entry point as a linker switch...Thoughts?Anybody have time to try? =D
