Hi

     Still time for this fix for gcc 12 ?

     If so I'll make sure to run tests quickly, especially the abi.exp 
one to confirm that the cleanup in gnu-versioned-namespace.ver do not 
need to be replaced by the same in __8 namespace.

libstdc++: [_GLIBCXX_INLINE_VERSION] Fix std::random_device definition

Definition shall be put in _GLIBCXX_BEGIN_VERSION_NAMESPACE/
_GLIBCXX_END_VERSION_NAMESPACE like the declaration.

libstdc++-v3/ChangeLog

     * src/c++11/cow-string-inst.cc: Put random_device member definitions
     in versioned namespace.
     * src/c++11/random.cc: Likewise.
     * config/abi/pre/gnu-versioned-namespace.ver: Remove std::random_device
     symbols.
