Thanks for the fixes, but please note that all patches for libstdc++
should be CC'd to the libstdc++ list, see
https://gcc.gnu.org/lists.html

Had you done that, I'd have pointed out that your first patch didn't
regenerate configure, and would have also noted the other problems
below ...

This typo exists in the upstream issue that the comment refers to, and
I'd prefer to keep it rather than "fix" it.

See https://cplusplus.github.io/LWG/issue1261

This file is generated from include/bits/version.tpl so this change
will be overwritten. I'll fix the template too.

This file is imported from a third-party project, changes to it should
be submitted there not just changed downstream in GCC.

I've created https://github.com/fastfloat/fast_float/pull/385 for the
first change (the second one was already fixed upstream).
