Dosn't make me wonder. E.g. a lot of variant arithmetic functions do not
like VT_INT as input variant; one accepts it only as left variant but
not as right variant. The oleaut dll looks to me like it wasn't designed
but just hacked up to make the VB frontend work.

If the function is supposed to accept VT_INT then yes.

VT_INT is 16 bits on 16bit Windows and 32bits in Win32.
