Should be {$ifdef unix}

See other answers, but for the case it is not alraedy predefined, yet it
works, also for crosscompile. However you should hardly ever use {$if(n)def
linux}, _always_ unix. 

The only exeception are really 100% linux only things which are relatively 
rare.

Yes, but not OS independant. Each OS has its own api for such things :-)
