1896// (IsSeekable() is implemented as wxGetFileKind() == wxFILE_KIND_DISK).

1898// This is important for the archive streams, which benefit greatly from
1899// being able to seek on a stream, but which will produce corrupt archives
1900// if they unknowingly seek on a non-seekable stream.

1903// disable features of the archive streams. Some other value must be returned
1904// for a file type that appears seekable but isn't.

1906// Known examples:
1907// * Pipes on Windows
1908// * Files on VMS with a record format other than StreamLF
