I'm not an expert on the windows unit but I encountered similar problems
among platforms and I think we should defenetly go for compat. The best
thing you can do (so nobody can say anything) is "complement" both ends.
So eg:

you got this in 2 windows unit:

W1. function A(const data): Pointer;

W2. function A(data: Pointer): Pointer;

Best is to complement both W1 and W2 so they both have both overloaded
versions. It's not nice, but this way you ensure 100% compat and
everyone is happy. Ofcourse since WINCE isn't stable yet it might be
cleaner to just copycat the windows ones into it.
