Clozure CL has no recently added `stream-file-position' in their gray streams implementation.

But it has `stream-position'.

I see that Helmut has already reverted this part.
For the record, the original proposal did not appear to mention *- POSITION <ftp://ftp.csl.sri.com/pub/users/gilham/stream-definition-by-user.mail
.
trivial-gray-streams calls this function STREAM-FILE-POSITION, as do CMUCL, SBCL, LispWorks <http://www.lispworks.com/documentation/lw51/LWRM/html/lwref-619.htm
, and ACL <http://www.franz.com/support/documentation/current/doc/streams.htm .
CLISP calls it STREAM-POSITION <http://clisp.cons.org/impnotes/gray-gf-general.html
, as does CCL apparently.
Some unification would be nice, and STREAM-POSITION is probably the better name because the operation can well be supported for non-file streams (flexi-streams uses the name FLEXI-STREAM-POSITION).

ACL 8.1 doesn't seem to implement a function STREAM-FILE-POSITION, despite the referenced documentation. When ACL tries to import *gray-stream-symbols* from EXCL, it fails to find that function. In analogy to the conditionals for :stream-line-length, I made :stream-file-position conditional in the list of *gray-stream-symbols* in swank-backend.lisp. I offer the difference below, but don't know if that's the best approach.
Thanks,
Steve

Helmut,
I see the ChangeLog entry, but STREAM-FILE-POSITION appears still to be in the code: +2008-08-31 Helmut Eller heller@common-lisp.net + + * swank-backend.lisp (*gray-stream-symbols*): Remove + stream-file-position because it's called stream-position in CCL. +
Should we make it #+(or sbcl cmu lispworks) for the time being?
Cheers, Michael

Changelog states this problem was fixed, but actual file wasn't modified:
* swank-backend.lisp (*gray-stream-symbols*): Remove stream-file-position because it's called stream-position in CCL.
