Phoronix: GCC Prepares For C17 Language Support

Not to be confused with C++17 that brings many notable additions and improvements, C17 is also coming soon as an update to the C programming language...

Anything new in C17?
Could it get anything new inspired by Rust?

Until a few months ago I've only read a few proposals for a C2x Standard. So I'm not sure what should be this C17/C18 new publication to be honest. Also, this document (http://www.open-std.org/jtc1/sc22/wg...docs/n2021.htm) mentions 2022 as the currently intended date for publication of the next full standard.

EDIT: well, Michael already posted this link in the article (https://gcc.gnu.org/ml/gcc-patches/2.../msg02121.html), so it's actually "a bug-fix version of the C11 standard with DR resolutions integrated".

Does this mean no binary literals for C17?

As far as I know the proposal for binary literals has always been rejected. However, GCC for example does have an extension that supports it: https://gcc.gnu.org/onlinedocs/gcc/B...nary-constants

C17 seem to be just corrections to C11 (though hard to tell, when I finally found the official proposal for consideration it was a password protected PDF). There are some new stuff proposed in C2x, but nothing major, they have officially decided to let C++ be the more ambitious language, and only do very minor housekeeping that fits into C's current capabilities.

There is a proposal to add closures to C. That would be pretty major, IMO. (They're drawing from both C++ and Objective-C as experience, I believe.)

C18 would sound better.

Funny enough, C99 had stdint.h, but it took until C++11 for C++ to get it (as <cstdint>), the divergent C++ standard actually lacks some important nuances from the C standard, it's pretty funny if you read both.

Nice to see GCC at the forefront of things and not badly behind LLVM and VC++ like it was with the C++11 adoption/implementation. I guess it goes to show that even open source projects need the occasional kick in the rear end from competition.
