Thanks. Very insightful. We got tarballs from
https://www.postgresql.org/ftp/source/v16.1/,
thus it could have been it indeed. We've rebuilt from scratch again, and
now things are back to normal.
I'm not 100% what fixed it exactly, since I get 2nd hand info only, and
thus don't know for sure whether
`make maintainer-clean` was used or not. Could also have been a glitch in
our SCM, we also forced a
resync on the workspace with 3rd parties (NFS mounted).

I any case, this is now resolved, albeit in a muddy way I'm afraid...

Really appreciate the help. Thanks, --DD
