Lazarus is not a compiler :) You can check if you are using fpc by
{$ifdef fpc}. Delphi does not have similar define but you can check for 
paticular delphi version using:

{$IFDEF VER120}      // Delphi 4.0

{$IFDEF VER130}      // Delphi 5.0

windows: {$ifdef Windows} or {$ifdef MSWindows}
linux: {$ifdef linux}
osx: {$ifdef darwin}

FileSetAttr or FileSetAttrUTF8 depends on how your filename string is
