#serial 1
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,
[AC_TRY_RUN([
# include <sys/types.h>
# include <sys/stat.h>

struct stat sbuf;
exit (lstat ("", &sbuf) == 0 ? 1 : 0);
