Thanks for this project, which is very useful!
./autogen.sh
on an Ubuntu 22.04 (autoconf 2.71) produces a number of warningsThis seems to be similar to https://gitlab.com/openconnect/openconnect/-/issues/413.
I see from the 2.71 announcement that there are some compat breaks with 2.69 and older, and this package currently targets >=2.61. See also the autoconf changelog.
