* Makefile.am: New file, based on old Makefile.in.
* acconfig.h: New file.
* acinclude.m4: New file.
* stamp-h.in: New file.
* configure.in: Call AM_INIT_AUTOMAKE and AM_PROG_LIBTOOL.
Removed shared library handling; now handled by libtool. Replace
AC_CONFIG_HEADER with AM_CONFIG_HEADER. Call AM_MAINTAINER_MODE,
AM_CYGWIN32, and AM_EXEEXT. Replace AC_PROG_INSTALL with
AM_PROG_INSTALL. Change all .o files to .lo. Remove stamp-h
handling in AC_OUTPUT.
* dep-in.sed: Change .o to .lo.
* Makefile.in: Now built with automake.
* aclocal.m4: Now built with aclocal.
* config.in, configure: Rebuild.
