-/* Win32 uses DWORD (32-bit) type to store size of string before (OLECHAR *) string.
-  We must select CBstrSizeType for another systems (not Win32):
-
-    if (CBstrSizeType is UINT32),
-          then we support only strings smaller than 4 GB.
-          Win32 version always has that limitation.
-
-    if (CBstrSizeType is UINT),
-          (UINT can be 16/32/64-bit)
-          We can support strings larger than 4 GB (if UINT is 64-bit),
-          but sizeof(UINT) can be different in parts compiled by
-          different compilers/settings,
-          and we can't send such BSTR strings between such parts.
