Hmm, there's a problem here. The leatherman package fails to build
against Boost 1.73.0 because the version of Boost.Nowide accepted into
upstream Boost doesn't have one of the headers in the standalone
nowide library:

/builddir/build/BUILD/leatherman-1.10.0/util/src/environment.cc:2:10: fatal 
error: boost/nowide/cenv.hpp: No such file or directory
     2 | #include <boost/nowide/cenv.hpp>
       |          ^~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Looks like it was replaced by <boost/nowide/cstdlib.hpp>:

https://github.com/boostorg/nowide/commit/5c684c0fe670fbf772e024817e562c8086621baf

Yes, as now used by leatherman:
https://src.fedoraproject.org/rpms/leatherman/c/629b826aa4d2dbd768d83d6f87d850cb7792f76a?branch=master

It's also necessary to link to libboost_nowide.so which wasn't needed
with the old boost-nowide package in Fedora:
https://src.fedoraproject.org/rpms/leatherman/c/d32134d9f5764503a1fff65cbf26606c4c20d051?branch=master

There's some difficulty for upstream projects currently using the
pre-Boost version of nowide if they want to be compatible with Boost
1.73.0, but nothing too onerous. Some relevant discussion at
