When there are changes to hdrgen like this in general, they should come with new test coverage in hdrgen/tests.

However, I don't think this is a change we want at all. The precedent for complicated types used in function signatures is to define typedefs for them. `__qsortcompare_t` is a very similar example to `scandir`'s argument type.
