Seems sensible.  I think I prefer something like

  eval `$LIBTOOL --config | grep 'shlibpath_var='`
  if test -n "$shlibpath_var"; then
    CPPFLAGS="$CPPFLAGS -DLT_MODULE_PATH_VAR=\"$shlibpath_var\""
  fi

over including toplevel config.h though; and using ifdef in the code, to
cater for systems without such a variable.

Again, please leave 48 hours for comments before committing.

Thanks,
