Warning on build tests

[ktrace]

When build v1.9.0 and later, I've got warnings:

GCC 14.2.1 20241221, x86_64-pc-linux-gnu

[gdamore]

This is from the ACU test framework. I guess new GCC does not like it. You can ignore for now as it is only the unit tests and not the actual product itself.

[gdamore]

Actually, this isn't ACUTEST, it's my old C-Convey framework. I've been moving code away from that gradually.

Stable doesn't have the benefit.
