Bug#787909: cl-asdf: breaks sbcl's included asdf.fasl

[Norbert Preining]

Package: cl-asdf
Version: 2:3.1.4-1
Severity: normal

Dear all,

I just found a problem due to both sbcl and cl-asdf being installed
on my system while building cafeobj (an interpreter built on-top
a CL interpreter, we are using sbcl).

The warning message lists something about *POLICY& and
there is a changelog entry in sbcl that there were
some changes.

The build here produces the following log:
...
; compiling file "/usr/share/common-lisp/source/cl-asdf/build/asdf.lisp"
(written 23 OCT 2014 05:15:20 AM):

I am not sure who should take some action here, but I thought I report it.

Thanks
