Ignore the above response.

See the definition of method for sb-gray:stream-file-position 
in the stream.lisp, under the #+sbcl

Note, that it works other way around, from sb-gray to trivial-gray-streams:

cl:file-position calls sb-gray:stream-file-position.
We define a method for it on our stream class;
and this method calls trivial-gray-streams:stream-file-position.
