Apologies if I am misunderstanding... It looks like what this patch does is already taken care of in upstream elinks -current.
So my current thought is that patch I sent is only needed/helpful for the version in 2026Q2 (and on (at least) hppa). In theory the current version of elinks should build on hppa. I could possibly test this - it will take me some time as I would want to do it in a separate system install.
Let me know if I'm missing something you are asking me for. Thanks.
