Wouldn't the approach you took on the meson side to pass
"-Wno-c11-extensions" be yet another alternative?  I think that is
what the other proposal (which was only for Makefile world and not
for meson world) did, even though it may not have been a great
implemenation to help only those who use config.mak.dev

We would need a patch to apply at lesat on v2.54.0 but possibly
older tracks if we plan to keep them also buildable.

Thanks.
