+Subject: [PATCH] Quick fix for changing of Hamlib's FILPATHLEN macro
+
+This patch was prepared for Guix by Jack Hill <jackhill@jackhill.us> by
+squashing together the changes from upstream #268
+<https://github.com/Tlf/tlf/pull/268>.
+
+It allows the released version of Tlf to build against the version 4.2 of
+hamlib in Guix.
