Annoying shadowing warning

[Jonathan Rees]

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.
