Mode ObjFPC is stricter in some cases. While mode Delphi cares for Delphi
compatibility.

That fixes it, but then the question is why does {$mode delphi} differ from
{$mode objfpc}?

[fpc-pascal] Error? No range checks in mode delphi?

[Anthony Walter]

Is the following a bug in the compiler or a feature? Is would seem using
{$mode delphi} allows code which clearly violates range bound to compile
without error.

program Project1;

{$mode delphi}

type
  TSuit = (suHeart, suDiamond, suClub, suSpade);
  TRedSuit = suHeart..suDiamond;

var
  Suit: TRedSuit;
begin
  // This should generate an error, but {$mode delphi} allows it
  Suit := suClub;
end.
