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
