It's saying that srfi-60 exports bit-count, but Guile already defined
bit-count. It then replaces the core definition (in your current module)
and proceeds.

It's just a warning, albeit a confused one:
http://article.gmane.org/gmane.lisp.guile.devel/10525. Fixed in git.

However `ash' is available in the default environment (see the manual),
and I think it optimizes better. Alternately you could:

  (use-modules ((srfi srfi-60) #:select (arithmetic-shift)))

or

  #:use-module ((srfi srfi-60) #:select (arithmetic-shift))

in a define-module form.
