Files in this directory:

  z            -- script that demonstrates the failure
  z.out        -- result of: ./z > z.out 2>&1
  z.LANG=C.out -- result of: ./z C > z.LANG=C.out 2>&1
  _inst/*      -- result of: ./z

The commands in z are originally from the GNU Automake 1.13.2,
test suite, specifically:

  t/install-info-dir.sh
  t/install-info-dir.dir/Makefile

To reproduce the failure, you probably need to have support
for the it_IT.UTF-8 locale installed.
