Are you sure? The NtCurrentTeb() function isn’t exported from x64 ntdll. If we export it from ours, then we have to export it on every x86-64 platform, because AFAICT there’s no way to say “Only export this function on Mac OS x86-64”.

Like I explained in the other thread, I’m just afraid that some program out there depends on NtCurrentTeb() not being exported from ntdll on x86-64. (Then again, if it depends on that, it probably depends on the TEB being accessible through %gs...)
