I have noticed that Christian has had the libtool 2.4.2 version bump in his 
staging repo since March 2019. I assume that it has caused no trouble for him 
so far, so I just wonder if it should be pushed to the main repo at some point?


Of the build tools we use, our version of GNU libtool (= "autoreconf" in our 
Makefiles) is by far the most antiqued tool that we still use. The currently 
used version 2.4.0 dates back to 2010. Bumping it up to 2.4.2 would advance 
it by one year to 2011, but it would still be quite antique.

I looked into the version bump work myself three years ago, but as there has 
been a major structure change after 2.4.2, I threw the towel in. Bumping it 
further from 2.4.2 to 2.4.6(?) requires some actual understanding of the 
Linux library environment and the intention of our OpenWrt specific 
cross-compile targeting patches for libtool.

I just fear that we will sooner of later get hit by the usage of a decade old 
tool as the related build tools and paradigms evolve. Bumping it up to 2.4.2 
might be the first step, but sooner or later somebody with relevant skills 
should look into getting the version modernized.
