/*
  p7zip and 7-Zip before v23 used virtual destructor in IUnknown,
  if _WIN32 is not defined.
  It used virtual destructor, because some compilers don't like virtual
  interfaces without virtual destructor.
  IUnknown in Windows (_WIN32) doesn't use virtual destructor in IUnknown.
  We still can define Z7_USE_VIRTUAL_DESTRUCTOR_IN_IUNKNOWN here,
  if we want to be compatible with old plugin interface of p7zip and 7-Zip before v23.

v23:
  In new 7-Zip v23 we try to be more compatible with original IUnknown from _WIN32.
  So we do not define Z7_USE_VIRTUAL_DESTRUCTOR_IN_IUNKNOWN here,
