6ab6acc does not compile on Delphi older than 10.3 Rio

Hi!

Compilation fails on Delphi versions older than 10.3 Rio here:

procedure TGpPreciseWait.ActiveWait;
begin
  var togo_ms := FDelay_ms - FStopwatch.ElapsedMilliseconds;

with this error:

[dcc64 Error] GpStuff.pas(3608): E2029 Statement expected but 'VAR' found

I've successfully compiled the code on Delphi 10.2 with this change:

procedure TGpPreciseWait.ActiveWait;
var
  togo_ms: Int64;
begin
  togo_ms := FDelay_ms - FStopwatch.ElapsedMilliseconds;

Fixed, thanks!
