[Bug]: 5.4.2 fails to build on 32bit

Describe the bug

Building the multilib package for Arch Linux (https://archlinux.org/packages/multilib/x86_64/lib32-xz/) fails. The lines producing the error did not change recently, but the version before (5.4.1) built without problems (and still builds with current toolchain).

Version

Operating System

Sorry. :-( I added a few warning flags since I thought I had silenced them all.

Arch uses --enable-werror so that's why warnings make the build fail. This is good for testing :-) although it can cause annoyances like this. It was only recently that -Wno-format-truncation could be removed from the PKGBUILD file in Arch.

It's fixed in master and v5.4 now. Thanks!

Thanks a lot for the quick fix!
