Thank you for your contribution.
Yes, it's (speed 3) (safety 0)
No, I haven't explicitly loaded any streams packages or anything
else. I'm just using what's supplied by default.
I'm not calling stream-read-char directly in my code, only read-char
(and unread-char).
I'm using cmucl mostly as one of a couple of Lisps for compatibility
testing. Most development is done with clisp; once a day or so I run
the source through cmucl and gcl to see what strangeness might be
detected. My source must be easily ported because the intent is to be
able to distribute it to neophyte Lispers whose choice of CL
implementation may vary.
My project is a new version of the old and decrepit Chess In Lisp
Toolkit. It's about 12 K lines long now and some code snippets can be

Is the above a spurious compilation diagnostic? The user function
works
fine.
Are you compiling this with speed 3 and space 0? You didn't say.
With
those settings, I get the compiler warnings.
They're real warnings because stream-read-char isn't defined because
that's for Gray streams, which, apparently, you haven't loaded.
I also get a warning about stream::%read-char. That's for
simple-streams, which you apparently haven't loaded either.
Without either of these modules loaded, you can't create streams of
that
type, so you can never execute that part of the code that would use
the
undefined functions. So, I guess they are spurious warnings.
