Perl problem w. pty: Can't install IO::Pty

[Henry S. Thompson]

Trying to upgrade App::Ack, ran into various odd test failures, but
that's a problem for another day, as notest install appears to work.

But in the test output, the fact that IO::Pty wasn't installed was
mentioned, so I tried to install it.  That failed at testing, as
follows:

  Running make test for TODDR/IO-Tty-1.14.tar.gz
  "/usr/bin/perl.exe" -MExtUtils::Command::MM -e 'cp_nonempty' -- Tty.bs
  blib/arch/auto/IO/Tty/Tty.bs 644
  PERL_DL_NONLAZY=1 "/usr/bin/perl.exe" "-MExtUtils::Command::MM"
  "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0,
  'blib/lib', 'blib/arch')" t/*.t
  t/pty_get_winsize.t .. Possible memory corruption: ioctl overflowed 3rd
  argument at /home/ht/.cpan/build/IO-Tty-1.14-0/blib/lib/IO/Tty.pm line
  72.
  # Looks like your test exited with 29 before it could output anything.

Not urgent, as I have ack working which is what _I_ care about, but
thought this was worth flagging up just in case it helps someone else.

cygcheck output attached.
