[$] Modern C for Fedora (and the world)

It can be instructive to pull down the dog-eared copy of the first editionof The C Programming Language that many of us still have on ourbookshelves; the language has changed considerably since that book waspublished. Many "features" of early C have been left behind, usually forgood reasons, but there is still a lot of code in the wild that is stillusing those features. A concerted effort is being made in both the Fedoraand GCC communities to fix that old code and enable some new errors in theGCC14 release (which is instage 3 of its development cycle and likely to be released bymid-2024), but a fair amount of work remains to be done.
