dnl From Jim Meyering.
dnl Determine whether lstat has the bug that it succeeds when given the
dnl zero-length file name argument.  The lstat from SunOS4.1.4 does this.
dnl
dnl If it doesn't, arrange to use the replacement function.
dnl
dnl If you use this macro in a package, you should
dnl add the following two lines to acconfig.h:
dnl  /* Define to rpl_lstat if the replacement function should be used.  */
dnl  #undef lstat
dnl

AC_DEFUN(jm_FUNC_LSTAT,
[
 AC_CACHE_CHECK([for working lstat], jm_cv_func_working_lstat,
