--- Comment #3 from g.peterh...@t-online.de --- >> libstdc++ doesn't depend on libquadmath and the __float128 support is there >> very limited. Yes, exactly. There should be nothing of quadmath in the std implementations of C/C++. But in bits/std_abs.h this is the case. >> Use std::float128_t instead (in GCC 13.1)? std::float128_t can only be used from C++23 on, but quadmath can also be used with older standard/compiler versions.
