perl 5.6.0 has, in Configure​:

  : Sanity checks
  case "$fastread$alldone" in
  yescont|yesexit) ;;
  *)
  if test ! -t 0; then
  echo "Say 'sh Configure', not 'sh <Configure'"
  exit 1
  fi
  ;;
  esac

where the check for $fastread being yes and $alldone being cont and
exit to disable the check is relatively new.

This check is still to strict; it should also be disabled in the case
of "./Configure -S".

From acme@astray.com

This is fixed in bleadperl. -S sets extractsh to be true and there is an extra check for
this in the code you pasted.
