Hello FPC-Pascal users discussions!

I have this conversion:

type TWordSet = set of 0..15;
     PWordSet = ^TWordSet;
var  btn: TMsgDlgButtons;
begin
  ...
  Integer(PWordSet(@btn)^) := Params[0]; // Params is Variant
  ...
end;

With FPC 2.4 it is OK, but up-to-date FPC SVN reports error in subject.

Is it a bug or it needs different conversion.

How can I fix it?

Thanks.

Best regards, TRoland http://www.rotursoft.sk http://exekutor.rotursoft.sk
