* aclocal.m4 (V5_SET_TOPDIR): In newer versions of autoconf

	(2.49), AC_LOCALDIR is not set by the reconfiguration process. If
	AC_LOCALDIR is not set, try to find the top of the tree by looking
	for aclocal.m4. If aclocal.m4 ever exists in a subdir, we will
	need to redo this test.

	* aclocal.m4: Upgrade to autoconf 2 naming schemes - AC_C_CONST,
	AC_CHECK_HEADER, AC_PROG_LN_S, AC_MSG_ERROR instead of AC_CONST,
	AC_HEADER_CHECK, AC_LN_S, AC_ERROR. Use AC_DEFUN instead of
	define() for macro definitions and better quoting of macros within
	macros.
