 	only if --enable-ltdl-install
	(CONF_SUBDIRS): list directories that are configured on demand,
	but that must be included in the distribution
	(ACINCLUDE_M4_LIST, DIST_MAKEFILE_LIST): generated from CONF_SUBDIRS
	* Makefile.am (AUTOMAKE_OPTIONS): added version 1.3e and
	readme-alpha, to handle README-alpha automatically
	(EXTRA_DIST): removed README-alpha
	(BUILD_SUBDIRS): subdirectories that are always built
	(SUBDIRS): BUILD_SUBDIRS plus BUILD_LTDL
	(DIST_SUBDIRS): BUILD_SUBDIRS plus CONF_SUBDIRS, from configure

	(configure-subdirs): new target
	(configure-subdirs, distdir): depend on $(DIST_MAKEFILE_LIST),
	from configure
	(@DIST_MAKEFILE_LIST@): create subdir if needed, then run
	configure.
	On-demand configuration of subdirs at distribution time was
	suggested by Gary V. Vaughan <gvaughan@oranda.demon.co.uk>
