* configure.in (AC_CONFIG_SUBDIRS): add libltdl, demo, mdemo and

depdemo commented out, so that `dist' works before `check'
	(BUILD_LTDL): will contain libltdl if --enable-ltdl-install
	* Makefile.am (DIST_SUBDIRS): expand SUBDIRS and add depdemo,
	commented out
	(SUBDIRS): add $(BUILT_LTDL)
	* libltdl/Makefile.am (EXTRA_LTLIBRARIES): add libtest.la, the
	same as libltdl but always a convenience library.  Not built by
	default.  Both libraries now depend on the libtool script, that
	depends on ../libtool and is rebuilt when needed
	* mdemo/Makefile.am (mdemo, mdemo.debug): depend on and link with
	../libltdl/libtest.la, that is rebuilt if needed
	(mdemo_LDADD): removed $(LIBADD_M), to avoid silent failures
	(foo1.la): renamed from libfoo1.la; test removing the lib prefix
	* mdemo/foo1.c: renamed libfoo1_LTX symbols to foo1_LTX
	* mdemo/main.c: don't include string.h nor math.h, nor refer to
	sin nor cos
	* tests/mdemo-exec.test: renamed libfoo1.la to foo1.la
	* tests/mdemo-inst.test: ditto
