[fpc-pascal] Fwd: Delphi incompatible conditionals?

I also noticed that. Strange. (delphi XE btw)

Try longint(3) and longint(2).

I think it belongs on the Embarcadero buglist more than here. OTOH, they
will only fix it in the current or next version. So that's why I tried till
I got above workaround.

Still, it might be worth a report, otherwise stuff never gets fixed. And
that goes both for FPC and Delphi :-)
