The logic is backwards here: _dos_findfirst returns zero when it
succeeds, non-zero otherwise.

Also, why do you use _dos_findfirst instead of findfirst?  The latter
supports long file names on Windows, while the former does not.

Why do you call _dos_findnext at all, if you have no use for the
results it returns?
