It was suggested by @ldionne in https://reviews.llvm.org/D153709 as a short-term solution.
BTW. can I link to inline comments in Differential?
================
Comment at: libcxx/include/sstream:341
- requires __is_allocator<_SAlloc>::value
- _LIBCPP_HIDE_FROM_ABI basic_string<char_type, traits_type, _SAlloc> str(const _SAlloc& __sa) const {
- return basic_string<_CharT, _Traits, _SAlloc>(view(), __sa);

It was an error to have this overload conditional on `_LIBCPP_BUILDING_LIBRARY` in the first place.
It shouldn't depend on `_LIBCPP_BUILDING_LIBRARY` because it doesn't conflict with the pre-C++20 `str() const` overload.
In this patch I change decorations of members under this condition, but this template method isn't problematic at all.
I put it here originally just to follow the order in the spec.
