--- Comment #107 from Sergey Fedorov <vital.had at gmail dot com> --- This is needed too: https://github.com/iains/gcc-16-branch/commit/1aabd474c7f58e069e49b6096056937389ba7b51 It is identical to what gcc16 port has: https://github.com/macos-powerpc/powerpc-ports/blob/f24237268895c848d177748ca88861dcde53c4f0/lang/gcc16/files/patch-libstdcxx-call_once.patch But Iain may have an updated version of it now.
