Annoying shadowing warning

Redefining an imported name is, in my opinion, a perfectly legitimate =
thing. I don't mind getting a single warning when the name is first =
shadowed, but I get this every time I load the file, even if it has been =
loaded before.

This behavior is not seen in version 1.4. Apparently there's no warning =
at all there. The warning is ok, its repetition is the issue.

This is in scheme 48 1.9 on a mac.
