I posted three patches back in March and I don't think anyone has looked at them: https://lists.gnu.org/archive/html/autoconf-patches/2020-03/msg00012.html https://lists.gnu.org/archive/html/autoconf-patches/2020-03/msg00013.html https://lists.gnu.org/archive/html/autoconf-patches/2020-03/msg00014.html These address Savannah issues https://savannah.gnu.org/support/?110210 and https://savannah.gnu.org/support/?110211 which are fairly important regressions from 2.69. It would be nice if someone could look at them soon. zw
