It’s part of GNU Gzip, and zcat is basically just a shell script that runs exec gzip -cd "$@" meaning you can actually just do cat /usr/bin/zcat to get the source.

The options that start with HAVE_ usually depend on the arch or compiler. I don’t believe it’s possible to enable manually without modifying the source itself.

firmware drivers

This sounds like you’re talking about firmware blobs that the kernel drivers load, which are usually in a package called linux-firmware. It should be updated automatically, but I’ll check in the morning with Fedora Silverblue.

Pretty useless unless you use KDE, but I really like KDE’s widgets.
