How so?  AC_FUNC_CLOSEDIR_VOID already does an
AC_REQUIRE([AC_HEADER_DIRENT]), so there is no change in output.

On the other hand, I wrote this patch prior to my subsequent patch to make
autoconf silent on the direct expand then require, and I suspect this
should fall in that category of warnings that were silenced.  So if
reverting just this patch is now silent, then it seems like the right
thing to do.  I'll be testing that tomorrow.
