But it would be handy if this was predefined (same as in the C# and Java
backends).

And, even if you don't want to provide function versions, the documentation
should be extended by a sentence or two. Saying that the macro versions are
problematic and that users should use foreign exports instead - or that they
should use inline functions, which wrap the macros, like it was discussed.
