Outdated libtool creates trouble on macOS

[FX Coudert]

Hi Marc,

> Sorry about that. I knew there were problems with old autotools and quickly tried updating them before the release, but that caused too many problems.

What are the problems? Our workaround is to rerun the latest autoreconf, and it emits a lot of warnings, but it does not create trouble. What are the symptoms you are seeing?

Can help if you let me know what you need.


One other question: our Linux builder, which is running from Github Actions, fails to download from gmplib.org
I thought only the mercurial repo was firewalled, is that not the case?

Best,
FX
