bug#43579: g++ does not provide std::fegetround

[Ludovic Courtès]

Hallo!

Andreas Enge <andr...@enge.fr> skribis:

> The following test file round.cpp does not compile with our g++-10.2.0:
> #include <cfenv>
> int main () {
>    return std::fegetround ();
> }

Could you provide detailed steps to reproduce it?

Thanks,
Ludo’.
