hi
this code compile without error in delphi mode , but raise an error of
incompatible type in objfpc mode .
how to get this code work in objfpc mode ?
Code: [Select]type
    PLongArray = ^TLongArray;
    TlongArray = array[0..1] of longword;
var
   map : ^byte;
begin
   GetMem(map,256*256);
   PlongArray(map)[1] := $ffff; // -Mobjfpc : Error : Incompatible
types : got "word" expected "TlongArray"
   FreeMem(map);
end. 


thanks

AUTODEREF is active for Delphi and TP mode, for compatibility reason.
