It looks like your patch is against gcc-14 not trunk, the

Sorry, I mean GLIBCXX_3.4.34 for 15.1.0
Oops that's what I used to test the patch. Reapplied to master now.
Ping - what's the status of this patch?
It would be nice to switch to the new ABI structure for std::call_once as
soon as possible, to ease a future switch to native TLS on mingw targets,
once https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80881 is done. (This
quirk with the exposed cross-DLL TLS data in std::call_once also comes up
in a number of other situations on mingw, so it would be nice to switch to
the new form where it is hidden.)
