No problem.

I've now built[1] the latest staging on F31, F32, and Rawhide (GCC 9.3
and 10.1) without issue (except a few -Wmaybe-uninitialized warnings,
but I didn't see any is_pod deprecation warnings).

One small discrepancy I noticed is that libbutl appears to have a
COPYRIGHT file in addition to AUTHORS and LICENSE files. Is this
intentional? build2, libbpkg, bpkg, and bdep seem to have created and
then removed the COPYRIGHT file during v0.13.0 development.
