2.72 isn't any better here and https://stackoverflow.com/a/27466219/696632 doesn't work either. Docs say (https://www.gnu.org/software/autoconf/manual/autoconf-2.68/html_node/Pretty-Help-Strings.html): > Macro expansion is performed on the first argument.

I tried to play around a bit with my humble knowledge, but was not successful. My assumption is that the help string is built during autoconf time while the variables are only available at configuration time. M
