But some more esoteric platforms may not have it. 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.
