Yeah, this is more interesting.

A leaner test case is icon-naming-utils.  If I build that with automake 1.17.0, it works.  If I build it _from clean_ with 1.17.90, it works.

If I build it with 1.17.0 and then autoreconf with 1.17.90, it fails.  Really mysteriously the generated aclocal.m4 has been regenerated (because the copyright dates are different) but it is missing the AM_RUN_LOG macro.

For bonus fun I _know_ the aclocal.m4 is regenerated as for historical reasons (that I plan on reviewing and potentially removing) we delete aclocal.m4 from the source before running autoreconf.

I have three complete build trees if you want to have a proper dig (with the release, with the alpha but on a dirty source tree built with the release, with the alpha from a clean source tree), but attached are the three different aclocal.m4 files as a demonstration of what is happening.

I see from comparison of the logs that the code triggering this ("checking how to create a ustar tar archive… gnutar”) isn’t in the log for the 1.17 build.
