--- Comment #10 from John David Anglin <danglin at gcc dot gnu.org> ---
No.  We still have the following symbols in tzdb.o:
                 U __atomic_compare_exchange_4
                 U __atomic_fetch_add_4
                 U __atomic_fetch_add_8
                 U __atomic_fetch_sub_8

There was this warning compiling tzdb.o:
../../../../../gcc/libstdc++-v3/src/c++20/tzdb.cc: In function 'std::string
std::chrono::{anonymous}::zoneinfo_dir()':
../../../../../gcc/libstdc++-v3/src/c++20/tzdb.cc:983:44: warning: the address
