riece-5.0.0で質問です。

以下の環境で、autoconfが動作しません。
Cygwin: 1.5.25
Autoconf: 2.63

$cd ~/cvs_work/riece
$ autoconf -i -f
configure.ac:4: error: possibly undefined macro: AM_INIT_AUTOMAKE
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.ac:6: error: possibly undefined macro: AC_CHECK_EMACS
configure.ac:7: error: possibly undefined macro: AC_PATH_LISPDIR
configure.ac:8: error: possibly undefined macro: AC_PATH_PACKAGEDIR
configure.ac:10: error: possibly undefined macro: AM_CONDITIONAL

どなたか、ご教授願います。
