guix - Wojtek's customized Guix

Adapted from Debian: https://sources.debian.org/patches/sqlite3/3.32.3-1/20-hurd-locking-style.patch
Upstream status: Not upstreamed.

This patch is needed to get offloading to work.

Sqlite can use simple file locking mode, but that does not work for the Hurd;
a second sqlite process fails with a "locking protocol" error.
