--- Comment #4 from Konstantin Belousov <kib@FreeBSD.org> ---
Created attachment 178484

=3Dedit
Provide __cxa_thread_atexit_impl(), split __cxa_thread_atexit() into separa=
te
.o.

This patch should help with gcc libstdc++ configured on stable/11 with
__cxa_thread_atexit() already existing in libc. With the patch applied, gcc
configure should detect __cxa_thread_atexit_impl() and generate only a wrap=
per
cxa_thread_atexit() for libsupc++.

If gcc was configured on system where __cxa_thread_atexit(3) was not provid=
ed,
but used on a system where it is, the patch does not make a difference.
