I'd like to know why that warning is being given before trying to 
suppress it, as it could be a valid version-mismatch warning for that 
user's build configuration.

For what it's worth, I don't get the warning when running the latest 
autotools-wrappers on Fedora 37. I got my copy of autotools-wrappers 
from <https://gitweb.gentoo.org/proj/autotools-wrappers.git/> commit 
afe80def609c91d72df73837ce2c51fed8b69f28. Perhaps the user in question 
could try that version of autotools-wrappers.

I'll cc this to Sam James to see if he has any advice about this. Sam, 
the thread is in <https://bugs.gnu.org/61782>.
