Hi
Any news regarding this problem ?

Hi
The few tests that are failing in versioned namespace mode are due to
those friend declarations.
This is a fix proposal even if I considered 2 other options:
1. Make __format::_Arg_store a struct and so do not bother with friend
declarations.
2. Consider it as a compiler bug and do nothing. In this case I think
we might still need this patch to avoid a non-working format library
in versioned namespace mode in gcc 14 if compiler bug is not fixed.
I can also define _GLIBCXX_STD_V at <format> level to limit impact.
libstdc++: [_GLIBCXX_INLINE_VERSION] Fix <format> friend declarations
GCC do not consider the inline namespace in friend declarations.
We need
to explicit this namespace.
libstdc++-v3/ChangeLog:
* include/bits/c++config (_GLIBCXX_STD_V): New macro
giving current
std namespace with optionally the version namespace.
* include/std/format (std::__format::_Arg_store): Use
latter on friend
declarations.
Tested under versioned mode.
Ok to commit ?
