I'm trying to drag one program at $employer up to C99 (plus C11 _Generic), so I can then subsequently drag it to the bits of C23 which GCC 13 supports.
This all takes times, and having to convince colleagues during code reviews.
What C23 has done is authorise some of the extensions which GCC has had for some time as legitimate things (typeof, etc).
However the ability to adopt is also limited by what third party linters in use at $employer may also support.
True, at most I read excerpts when I have a question. Can you tell me what gave it away? I thought the saying is that C17 is the sane version of C11 and C23 has quite some changes, but is way to new to be counted on.
C17 is indeed a bug fix release. C23 finally removed some features that were deprecated a long time ago already in the first standardized version (auto as storage classifier, K&R function definitions, empty parenthesis as "arbitrary arguments") and also support for ones' complement. So yes, C is extremely backwards compatible.
