Error starting sbcl under slime on Vista - emacs

Question

I'm having trouble getting SBCL to start under slime. I've messed things up and I don't know how to recover. This was working fine until I...
Had a problem loading a package via asdf. At which point I started debugging the asdf.lisp provided with SBCL to see what was going wrong. The sole change I made was to put a (break) in which I removed once I'd figured out what was wrong. All was fine until the next time I tried to start SBCL.
Then I got a swank compilation error saying that the asdf.fasl was older than the asdf.lisp file. That made sense to me so I recompiled the asdf.fasl. The output I'm now getting is:
(progn (load "c:\\emacs-23.1\\site-lisp\\slime\\swank-loader.lisp" :verbose t) (funcall (read-from-string "swank-loader:init")) (funcall (read-from-string "swank:start-server") "c:\\Users\\GILESR~1\\AppData\\Local\\Temp\\slime.3068" :coding-system "iso-latin-1-unix"))
This is SBCL 1.0.37, an implementation of ANSI Common Lisp.

So it's not finding some stuff it needs in my recompiled asdf. In order to resolve this I've done a complete uninstall and reinstall of SBCL. No joy. I've got nothing in my .sbclrc either.
Update: On viewing the asdf.lisp source code the missing functions are definitely in the file. The thing that's preventing them from compiling is I think the line:
#+(and sbcl sbcl-hooks-require)
My knowledge of lisp is currently not sufficient to compile the asdf file in the environment to trigger the above conditional compilation statement.

Answer 1

I've sorted the problem using the following steps:
Fire up sbcl from Windows start menu.
Run the following code to add the sbcl-hooks-require symbol to the feature list:
(push :sbcl-hooks-require features)
Recompile asdf.lisp. In order to do this I needed to recompile asdf outside of the installed C:\Program files\Steel... directory as the UAC on Windows Vista will stop the fasl being written. For example:
(compile-file "C:\foobar\asdf.lisp")
Copy the generated fasl back to C:\Program files\Steel... to overwrite the original fasl.
Update: The formatting on stackoverflow has knocked out some of the code bits. The code should be as follows:
(push :sbcl-hooks-require *features*)
(compile-file "C:\\foobar\\asdf.lisp")
