That's incorrect.

$ cat tt3.pp
{$r+}
procedure test;
var
  b: byte;
begin
  b:=255;
  b:=b+1;
end;

begin
  test;
end.

$ ppcx28 -gl tt3
Target OS: Linux for x86-64
Compiling tt3.pp

$ ./tt3

One thing to keep in mind: FPC's way of handling DWARF debug information (which is used by default on Linux/x86_64) is incompatible with smart linking. FPC 2.5.1 and 2.4.2 automatically disable smart linking when using DWARF debug info (and prints a warning about this), but FPC 2.4.0 may not yet do that.
