dnl this macro
dnl - defines and AC_SUBSTs [$PREFIX]_MAJOR, MINOR and MICRO, derived from version passed to
dnl   AC_INIT
dnl - if RELEASE is 1, then we're in release mode, else in cvs/dev mode
dnl - defines and AC_SUBSTs [$PREFIX]_RELEASE, 1 if release, date otherwise
dnl - defines and AC_SUBSTs [$PREFIX]_IS_RELEASE, 1 if release, 0 otherwise
dnl - executes the relevant action
