Yes, I have understood, for *your* application, you prefer something
else.  Since I will not change the semantics of the first parameters
(set since 2.50), since you don't like m4_define, the easiest remains
introducing a fourth parameter:

/tmp % cat configure.ac                                          nostromo 17:49
AC_INIT(GNU Foo, 1.0, fofo, fooooo)
echo m4_defn([AC_PACKAGE_NAME])
echo m4_defn([AC_PACKAGE_VERSION])
echo m4_defn([AC_PACKAGE_BUGREPORT])
echo m4_defn([AC_PACKAGE_TARNAME])
/tmp % $ace/tests/autoconf                                       nostromo Err 2
/tmp % ./configure                                               nostromo 17:49
GNU Foo
1.0
fofo
fooooo
/tmp % ./configure --version                                     nostromo 17:49
GNU Foo configure 1.0
