question about ryu support in gcc? ( pure-'C' )

[newbie-02]

do I understand the comment from STL on std::to_chars #199 (comment) correctly that g++ and clang++ use ( can use ) ryu but 'pure-C' gcc does not have this option?
if so, are there plans to implement that - and since here is not necessarily the right forum for that, where should you ask.

The code in this repository is pure C, but it doesn't implement the full std::to_chars standard. I'm generally happy to accept contributions, but I have very little time to work on it right now.
