Works for me too. Thanks!

I see, but it still doesn't answer my initial question. :-(

But then that's a bug in FPC's documentation! Chart.pdf shows "XX = $SMARTLINK = Use smartlinking." Btw: Did you receive my mails from last Friday?

That would be OK, but the problem is that not all command-line options have a source-code equivalent. So I have to use a mixture of both. That's what I dislike.
