Yes, I do know the matter. But I'm NOT changing dialect on my DBs!! They
are still dialect 1. The fact that the old dll works great is of course
related to that. All the UDFs used to get a "DATE" parameter, that
explain the PISC_QUAD type used in the Pascal code, parsed by
isc_decode_date().

I'm going to inline the isc_decode_date in the meantime... :-/
