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.
