[Openmcl-devel] stream-external-encoding: mythical beast?

Documentation says:

  9.1.1. Stream External Encoding

  Clozure CL streams have an external-encoding attribute that may be
  read using STREAM-EXTERNAL-ENCODING and set using (SETF 
STREAM-EXTERNAL-ENCODING).

I'm using 1.5-r13651 on Linux, 32 bit. There are no such functions.
