Hi!
One more thing about these.
Shouldn't we change those 3 even in non-TLS builds from errno@@GLIBC_2.0
to errno@GLIBC_2.0 etc., so that new programs accessing these directly
simply don't link anymore?
Jakub

Yes.

Unless I missed something, I didn't see any rationale about your moving the
TLS symbols to GLIBC_PRIVATE.

I've done this. But libpthread.so needs to refer to them, so I will have
to do some kind of funny business to make that work.

Hasn't been discussed in mail. Jakub and I had a chat on IRC yesterday.
Exposing STT_TLS symbols seems unnecessarily risky in the moment. I
want to do some more studying of the effects before we do that.

Ok, seems sensible. We already don't declare the __thread vars in any
installed header, so no program has any business using them.
