* io/unix.c: Defines for MINGW stat and fstat.
(gfstat_t): New typedef.
(id_from_fd): Use gfstat_t instead of struct stat.
(fd_to_stream): Likewise.
(compare_file_filename): Likewise.
(find_file): Likewise.
(file_exists): Likewise.
(inquire_sequential): Likewise.
(inquire_direct): Likewise.
(inquire_formatted): Likewise.
