Well, if it's just his opinion, I second it.  Libraries should return an
error to the caller, *not* print messages to some arbitrary file
descriptor (stderr in this case) which the caller may or may not still
have open.

I don't know if we have that documented as a standard for our library, but
we've followed it as an accepted standard to date anyway.
