I don't think this is really about GCC extensions (or obsolete language modes) rather than using the flexibility of the syntax to write things in a confusing way.
The first is simply K&R definitions + strange formatting.
- nneonneo 2mo agoOnly the first one is fully standards-compliant C; the others all invoke some non-standard (but widely-accepted) features. (I believe empty unions - and their interpretation as being 0-sized - are non-standard in C, but I am not 100% sure.)
- uecker 2mo agoMy point was not that those are standards-compliant, but that the use of the GCC extensions is not the primary cause of those examples being unreadable. (which seemed to be the point the person I replied to was making - and I disagree with GCC extensions being bad).
- icedchai 2mo agoI always forget K&R syntax is still in there. I taught myself C in 1988, during the K&R -> ANSI transition. All my early Amiga C programs were K&R style.
