I made the mistake of upgrading from Fedora Core 4 to Fedora Core 5 and
now a number of programs are broken, including gnat:

# cat zz.adb
with Ada.Text_IO;
use  Ada.Text_IO;

procedure zz is
  N : Natural;
begin
  N := Natural'Last;

  Put_Line ("Natural ranges from 0 to " & Natural'Image (N));
end zz;

# gnatmake zz.adb
gcc -c zz.adb
