  SVN rev 220376 on 2011-04-05 21:56:05Z by jilles
  
  Allow strerror(0) and strerror_r(0, ...).
  
  Of course, strerror_r() may still fail with ERANGE.
  
  Although the POSIX specification said this could fail with EINVAL and
  doing this likely indicates invalid use of errno, most other
  implementations permitted it, various POSIX testsuites require it to
  work (matching the older sys_errlist array) and apparently some
  applications depend on it.
