In my mail, I was suggesting that a return value of (size_t)(-1) is returned
only with errno = EBADF, not with any of EILSEQ, EINVAL, E2BIG.

I've submitted a clarification request to the OpenGroup guys. For the moment,
as long as they haven't clarified, libiconv and glibc's iconv continue to
return -1 whenever they set errno.
