* configure.in: turn on -Werror by default. We're now clean. I'd

Browse source 
like to stay that way.  If we want, we can turn it off by default
when we make the stable release, but I caught a lot of bugs this
way.  Accomodate libguile-ltdl -- therea are some ltdl things that
are commented out now INCLTDL and LIBLTDL.  I think we may not
need them anymore, but I'll leave them until we're sure.  We also
killed off the libltdl dir and related options including the
AC_CONFIG_SUBDIRS.  I also added some explicit tests for some
headers and functions that weren't listed but were in
scmconfig.h.in. though this may have been unnecessary.
