BTW, the DWORD typecast is only necessary with fpc, the following 
program gives 4 and 4 if compiled with delphi 2, 4 and -4294967292 if 
compiled with fpc 3.0.4


program project1;

uses
   windows;

var t1,t2,t3:dword;
begin
   t1:=$fffffffe;
   t2:=2;
   t3:=t2-t1;
   writeln(t3);
   writeln(t2-t1);
end.
