Thanks for the reminder.

I looked a bit at "fixing" libasync-interrupt-perl, noted that it uses
SIG_SIZE for other things too and decided I don't want to spend my time
on that.

My plan is to use the attached workaround, which should keep the ABI
regardless of the glibc version. It should probably go to sid soon.

I don't think Breaks are needed. The issue only happens if the current
perl gets built with the new glibc. Assuming we upload the workaround
to sid before glibc 2.26, I think it should be fine.

Thoughts welcome.
