For example, doxygen defines `register` to shut up an error due to it being
deprecated/removed in ISO C++ 17, but that causes issues with this
construct, which is an extension and still supported.
Fixes: f0044963d7ba ("headers: Use register variable for NtCurrentTeb
implementation on aarch64.")

Is this OK, or does it need any other preprocessor checks before using
push_macro/pop_macro? I grepped for other usages and it seems like this
is how it's done...
