dnl From Jim Meyering.
dnl Determine whether stat has the bug that it succeeds when given the
dnl zero-length file name argument.  The stat from SunOS4.1.4 and the Hurd
dnl (as of 1998-11-01) do this.
dnl
dnl If it does, then define HAVE_STAT_EMPTY_STRING_BUG and arrange to
dnl compile the wrapper function.
