Commentary

Hi, hopefully I've not missed something and this is a real bug. I think the example is quite clear. I would have a crack at fixing the issue on my own, but the debugging output has sufficiently terrified me.

The example is derived from erfam.h, although this include file gets pulled in from erfa.h in the same directory (so only erfa.h is needed to be fed to bindgen).

Thanks for bindgen!
