Shoot - I missed another POSIX requirement:
"The implementation shall behave as if no function defined in this
volume of POSIX.1-2008 calls strerror( )."
That is, strerror_r() cannot call strerror() (but we _can_ have a helper
method that both strerror() and strerror_r() call).
The POSIX requirement means that someone can replace strerror() with
their own link, but doing so won't affect the behavior of strerror_r().
Is this something that I should worry about and clean up in a followup
patch? Or is it too much of a corner case to bother with?
