* ehu reports on work on abcl-1.1.0 for 20120805

All in all a pretty good result for one week. However, from here on
$WORK will start again which means I'll only be able to address the
bigger issues in small steps. Or just the smaller issues, of
course. Which is why I'm glad to have worked out the D-M-C stuff. That
was a week more than full time work to completely comprehend the spec
and macrology going on in our implementation.

** Work on DEFINE-METHOD-COMBINATION can be considered Done

I left some todo's behind which should be relatively small in
comparison to the original problem. It's now just a matter of changing
the symbols in the backquote patterns.

** Autoloader rehab completed

My work on the autoloader has been mostly done as far as our current
infrastructure allows

***  next steps:

**** Clean autoload.lisp for any symbols which automatically end up in autoload-gen.lisp

**** Create infrastructure for autoloading of SETF functions (ie function names not designated by a symbol)


** Crashes evaluating a form referencing an undefined function in a clean image 

Solved by requiring PRINT-OBJECT in the right place With respect to
this point: it's possibly a good idea to do a search of the code base
and find out if we're doing this everywhere PRINT-OBJECT methods are
being defined

** COMPILER-UNSUPPORTED-FEATURE-ERROR derived from CONDITION 

solved

** Autoloader fails when *READ-xxx* variables bound to unexpected values 

solved

** Implement USE-FAST-CALLS properly 

Resolved by deleting the USE-FAST-CALLS infrastructure from the
interpreter; the compiler already does the right thing

** Compiling #n# causes stack overflow 

 Stas Boukarev reports that the case I've fixed only fixes in-memory
 compilation and the issue still exists in file
 ¯compilation. Ticket #191 should be re-opened to and should say so.
