{ Code below is copied from FPC 2.0.3 rtl/unix/sysutils.pp.
It has fixed GetAppConfigDir and GetAppConfigFile, so that
1. config file is stored inside hidden dir
2. moreover it follows base-dir spec
Michalis send this patch to FPC and it was applied during FPC 2.0.3
development. So for FPC 2.0.0 and 2.0.2, we need the workaround below. }
