The lack of complaints about this suggest that it's not actually necessary
to do so. So what this makes me wonder is whether we can't drop the
DLLEXPORT on the finfo function too. I'd rather reduce the number of
Microsoft-isms in the code, not increase it.

It seems like an obvious typo. Or, possibly, sloppy thinking that
contributed to failure to recognize that the keyword isn't needed.
