let/let* environments aren't properly seen in profiling mode

[sjamaan]

When compiling the following code in profiling mode, csc gives an error claiming "a" is undefined. Here's a simplified example:

(module whatever ()
 (import chicken scheme)
 (let ((a (lambda (x) (print x))))
   (a "ok")))

It doesn't give an error when there's no module surrounding it. Wrapping the let in a procedure doesn't help.

letrec instead of let[*] works, though.

The fix in experimental works great.
