  REBARBANDINFO in vista (_WIN32_WINNT >= 0x0600) has additional fields
  we want 2000/xp compatibility.
  so we must use reduced structure, if we compile with (_WIN32_WINNT >= 0x0600)
  Also there are additional fields, if (_WIN32_IE >= 0x0400).
    but (_WIN32_IE >= 0x0400) is expected.
  note:
  in x64 (64-bit):
  {
    (108 == REBARBANDINFO_V6_SIZE)

    (128 == sizeof(REBARBANDINFO) // for (_WIN32_WINNT >= 0x0600)
    there is difference in sizes, because REBARBANDINFO size was
    not aligned for 8-bytes in (_WIN32_WINNT < 0x0600).
    We hope that WinVista+ support support both (108 and 112) sizes.
    But does WinXP-x64 support (108 == REBARBANDINFO_V6_SIZE)?
