Yes, I know.

You are not supposed to access FILE directly, it's opaque simply to
avoid any stupid uses. E.g. you can't copy a FILE object to a different
location and expect it work, you can't just access it (because the
layout is opaque), the only valid way to create a FILE is via stdio --
so what should sizeof(FILE) be allowed for?

The reason why I haven't fixed ruby is that I don't have any idea what
they use it for.
