Ah, I see.

If Mono.Posix has it, that seems to be enough.

Correct. In my opinion, this needs some "glue" support in C, to have
the C compiler assist us when we port to an OS that has different fields
(as you noticed fsusage.[hc] has that).
I do not know if Mono.Posix today does it, if it already does, then we
are set to go

Not needed, just use an if based on the platform.
