I have a solution now, but I got a suggestion from the Embarcadero
forum to check Synopse and there I found a single file (plus an inc)
solution to my problem.
I downloaded the PasZip.pas and Synopse.inc files from this location:
http://synopse.info/fossil/dir?ci=tip
(Actually the inc file would not download so I copied the contents
from the website display instead into a file)
This is the function I ended up with and it works just fine:


function TSSCommHandler.ZipFiles(TargetFile: string; FileList:
TStringList): boolean;
{This function uses the Synopse files PasZip.pas and Synopse.inc to
create the zipfile.
Files were obtained from http://synopse.info/fossil/dir?ci=tip}
var
  ZW: TZipWrite;
  i: integer;
  FileName: string;
begin
  Result := false;
  ZW := TZipWrite.Create(TargetFile);
  try
    try
      for i := 0 to FileList.Count-1 do
      begin
        FileName := FileList[i];
        if not FileExists(FileName) then Continue;
        ZW.AddDeflated(FileName);
      end;
      Result := true;
    except
      on E: Exception do
      begin
        FLastError := 'Zip error: ' + E.Message;
        exit;
      end;
    end;
  finally
    ZW.Free;
  end;
end;

I am only interested in the creation of the zipfile, but there is a
reader class available too.
