I just noticed that for some reason I did not receive your message [1]
regarding the read-only variables issue [0].

It turns out that your patch is fine with Bash because Bash simply
prints an error message and then goes on executing the script.  However,
Tru64's, IRIX' and HPUX' /bin/sh really _stop_ the script.  In other
words, the following script prints "hello" when /bin/sh is Bash, and
doesn't otherwise:

  readonly ENV
  unset ENV
  echo "hello"
