Package: ruby3.1
Version: 3.1.2-7
Severity: important
Tags: patch

Hello,

ruby3.1 fails to build against glibc 2.38:

strlcat and strlcpy were indeed added to glibc in version 2.38, so it's
not surprising that ruby3.1 doesn't define its internal versions any
more, and the attached patch can probably be applied?
