Includes added or removed where necessary. Win16 functions replaced with their Win32 counterparts. Comments added where it was impossible. CALLBACK added where necessary. Some declarations fixed. Constructs like "#if WINDOWS" corrected. Using "#ifdef __unix__" instead. DlgProc in hello3 uses EndDialog() instead of DestroyWindow(). Listbox enabled in hello3.
