Re: issue CONSTANT-CIRCULAR-COMPILATION, version 4

	I guess I was envisioning that you would have to set *DUMP-CIRCLE* before
	calling COMPILE-FILE, and that tweaking it during compilation probably
	wouldn't do anything interesting.  Cris?

David Gray makes in interesting point in my opinion.  My thinking has
been more like yours, but on second thought, it is more appropriate
for the source file to specify the value of *dump-circle* rather than
some operation.

Regardless of the disposition of COMPILER-LET, I think the proposal had
better also say that *dump-circle* is rebound to its current value at least
during COMPILE-FILE.  That way a source file can (eval-when (compile)
(setq *dump-circle* t)) if it contains circular structure.
