cl-trivial-features 20200702.gite7bb968-1 (amd64 binary) in ubuntu jammy

 trivial-features ensures consistent *FEATURES* across multiple Common
 Lisp implementations.
 .
 For example, on MacOS X platforms, while most Lisps push `:DARWIN` to
 `*FEATURES*`, CLISP and Allegro push `:MACOS` and `:MACOSX` instead,
 respectively. Some Lisps might not push any feature suggesting MacOS
 X at all. trivial-features will make sure all Lisps will have
 `:DARWIN` in the `*FEATURES*` list when running on MacOS X. This
 way, you can write
 .
    #+darwin foo #-darwin bar
 .
 instead of
 .
    #+(or darwin macos macosx) foo
    #-(or darwin macos macosx) bar
