In principle, having autoconf/automake locally is normal as the distro's version too new. >>> I suspect the issue could be related to platforms where `off_t` is 32-bit, >>> causing a left shift of 62 to result in undefined behavior. The commit at https://cgit.git.savannah.gnu.org/cgit/autoconf.git/commit/?id=a1d8293f3bfa2516f9a0424e3a6e63c2f8e93c6e >>> seems to support my theory. As that commit is from 2020 and 2.69 in from 2012, it seems as if your autoconf is too new. Can you re-check that the right version is at the beginning of the PATH? Note that there is a CI job that checks whether the generated files are in deed up to date, i.e. the current trunk should be fine unless someone has messed up. The other question is whether the autoconf version shouldn't be updated, given that 2.69 is quite old. Tobias, currently a less active due to FTO.
