I stand corrected. I've just checked Delphi5 and indeed it allows a
direct typecast from ansistring to any object/class :-/
But Delphi also allows direct cast from enumeration value to pointer
(which FPC doesn't allow), so maybe this is another nice oportunity to
be stricter than Delphi ;-)

No.

Thanks.
So the trick to get convert a Pointer to an ordinal is to add/subtract
something. For example:
i:=PtrInt(p1-nil);
Is there a better trick?

I want to compute the offset/difference between two pointers. But I didn't
found a way to do that without compiler hints.
unit1.pas(42,6) Hint: Conversion between ordinals and pointers is not
portable
var
p1, p2: pointer;
i: PtrInt;
begin
...
i:=PtrInt(p1)-PtrInt(p2);
...
end;

FPC supports sse and sse2. sse3 gives no real advantage for a compiler.
