Hmm, but we don't set -Wpedantic in the first place. Is guix doing that?

I've never heard of gash before, but...

https://savannah.nongnu.org/projects/gash/
"Gash is designed to bootstrap Bash as part of the Guix
bootstrap process."

This makes me nervous that it may be internally doing Magic Things™ to
advertise itself as bash in some way that the configure script or
Makefile gets fooled by.

If you can figure out just why this happened, and/or a way to reliably
ensure bash itself is detected instead of gash, then we might be able to
fine-tune our detection algorithm.

Great!
