Hi Bruno, Thanks for testing yet another host configuration!

Amusingly enough, GNU diffutils 3.9 doesn't work either (it managed to break the -D option, upon which gdiffmk strongly depends). I'm on the fence about just documenting this as a known failure along the lines of the existing GNU diffutils 3.9 caveat, or trying to have the test script parse the diagnostic output of "diff" to decide whether it can skip the test. When people replace a GNU userland with a deliberately less featureful one like BusyBox (or ToyBox, or some other copyleft-allergic initiative), they have to be prepared for some reduction in functionality. A smaller memory footprint usually means fewer features. And every freedom has a price, including the freedom to extract unbounded economic rents via government-backed monopoly schemes.
