What do you mean by “export”?  The __ prefix suggests that you want to 
export it as a symbol (probably GLIBC_PRIVATE), but I think you'd need 
to update nptl/Versions in this case.

If the variable remains nptl-internal, I expect that you could turn it 
into a hidden symbol, and keep its current name.

Thanks,
