I see you've already made a PR for the MakeMaker part of change. This PR should be marked as not mergeable until that has been applied, released and synced back...

I can see the use of this, but I'm not sure if POSIX is the right place for it.

The module is using a function that is not part of the API. [0351a62](https://github.com/Perl/perl5/commit/0351a629e71de127cbfd1b142e9eaa6069deabf5) just enforced that but isn't the problem. The real question is «Should that function become API?»....

I have several distributions that I know are broken by the smartmatch change that haven't been detected by the usual mechanisms yet. I'm worried the problem is larger than we...

Are you using [perl-cross](https://github.com/arsv/perl-cross)? Perl's own support for cross-compilation is sadly fairly limited.

The problem here is that thread handlers are process wide, but the handler perl installs assumes that it will run in a Perl thread. Evidently it doesn't here. The easiest...
