--- Comment #13 from Jonathan Wakely <redi at gcc dot gnu.org> --- Please don't change src/c++17/fast_float/fast_float.h either, that's also a third party library, and your change is completely unnecessary. The libstdc++ code that includes fast_float.h already does: src/c++17/floating_from_chars.cc:# define FASTFLOAT_DEBUG_ASSERT __glibcxx_assert So it's already using __glibcxx_assert and not assert. The third party library does exactly the right thing and allows its assertions to be tailored to the project's preferred form. And we do that. So you don't need to change the code, it already does what you want.
