Otherwise we only use strtod/strtof. In 3 spots I've used fast_float namespace stuff unconditionally in one function, which breaks the build if fast_float is disabled. 2022-11-23 Jakub Jelinek <ja...@redhat.com> PR libstdc++/107811 * src/c++17/floating_from_chars.cc (__floating_from_chars_hex): Guard fast_float uses with #if USE_LIB_FAST_FLOAT and for mantissa_bits and exponent_bits provide a fallback.
