[fpc-devel]Delphi incompatibility again!

It is true but if we don't use tricks. Example:

const
 x:array[0..1]of longint=(1,2);
var
 y:longbool;
 s:string;
begin
 readln(s);
 y:=s<>'';
 writeln(x[longint(y)])
end.

This sample is very abstract, of course. It will work correctly only compiled with FPC. But if x will be defined as
array[-1..0]of longint, only Delphi-compiled version will work properly.
