It would have been nice to keep these macro around for backward

Fair enough. I installed the attached into Autoconf on savannah, so that
one should be able to use bleeding-edge Autoconf on the current RCS release.
This patch uses m4_define rather than AU_DEFUN because
_AC_SYS_LARGEFILE_TEST_CODE is defined via m4_define rather than via
AC_DEFUN. So the user is not warned that _AC_SYS_LARGEFILE_TEST_INCLUDES
is obsolete. I don't know why _AC_SYS_LARGEFILE_TEST_CODE doesn't use
AC_DEFUN, so I'll cc this to Zack (who wrote that code) to see whether
we can change to AC_DEFUN and AU_DEFUN here.From 938f2d844515a7cbc8ba3d40d0e57bfce9971969 Mon Sep 17 00:00:00 2001
