And here's the followup for m4 to use it.  Gary, if you could, please
rerun 'gnulib-tool --import' (or bootstrap), and see if it helps solve
your test failure?

Nope, sorry :-(

And rerunning the test by hand yields:

] ls

] echo $?

cpp turns fflush.c into something like this:

int
rpl_fflush (FILE *stream)
{
  int e1;
  int e2;
  int result;





  e1 = (*__error());
  result = fflush (stream);
  if (! stream || result == 0 || (*__error()) != 9)
    return result;


  e2 = (*__error());
  if (fseeko (stream, 0, 1) != 0)
    {
      (*__error()) = e2;
      return (-1);
    }




  (*__error()) = e1;
  result = fpurge (stream);
# 95 "../gnu/fflush.c"
  return result;
}

        Address failure of 'seekable stdin' on Mac OS X.
        * ltdl/m4/gnulib-cache.m4: Augment with 'gnulib-tool --import
        fflush.

Unfortunately, I can't even fix today's tree by hardcoding an fpurge
as I did when I reported the bug earlier.  I'll have time to roll


In the meantime, I'll be happy to run tests and report results if
you'd like to debug it remotely...

Cheers,
        Gary
