Hi Bogdan, In reference to: https://lists.gnu.org/archive/html/automake/2023-07/msg00007.html.
Thanks much! Since it's Autoconf 2.70 that started using the parameter, I've bumped the required value. I don't think we should require the brand-new ac 2.70 just for this minor feature. And I think it should be feasible not to: if the autoconf version is >= 2.70, your new code runs; if <2.70, just ignore any given argument. That way people can use the new automake macro with an older autoconf. I'm no expert on checking autoconf versions, but from glancing through the autoconf manual, it looks like m4_version_prereq might be the simplest to use in this case. It was officially added in ac 2.66, which should be old enough. It's described at the end of https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.71/autoconf.html#Number-processing-Macros Wdyt? Can you tweak your patch along these lines? Thanks again, Karl
