Cool, feel free to open an issue there, I don't want to have to wait weeks or months for a fix.

_(picking a line)_
Should this macro expansion use #_atf_expected, #_atf_actual instead of #expected, #actual? It shouldn't matter, except with non standards conforming C/C++ toolchains.

No, that wouldn't work since _atf_expected and _atf_actual aren't macro parameters, and I don't see why you'd want to.
