Missing Data type NativeUInt or UInt64

[KaterMusch]

I'm missing the data types NativeUInt or UInt64. Is there a reason why Int64 exists but UInt64 not? Can anyone help me with this?

Thank you

maybe so

uPSCompiler.pas

procedure TPSPascalCompiler.DefineStandardTypes;

{$IFNDEF PS_NOINT64}
  AddType('NativeInt', {$IFDEF CPU64}btS64{$ELSE}btS32{$ENDIF});
  AddType('NativeUInt', {$IFDEF CPU64}btS64{$ELSE}btU32{$ENDIF});
  AddType('UInt64', btS64);
{$ENDIF}

Unfortunately the data type "btS64" is not compatible with an Unsigned Int64. I could already test this.
I think I will try to introduce a new datatype btU64. At first sight it just looks like a lot of writing...hopefully without hidden traps.
