I think Werner already tried that and it faile on type Currency in
Win64 with fpc 3.2.2.
See https://gitlab.com/freepascal.org/lazarus/lazarus/-/issues/39490

Also, overriding is needed for anything with a range > Single, so you
only spare yourself the implementation in TSpinEditEx, where you could
do a simple A=B comparison.
