[Sbcl-devel] defclass patch

[Martin A. <ma...@at...>]

Attached is a patch for defclass, preventing bogus warnings about
redefining class-predicates in the interpreter.

EXPAND-DEFCLASS now uses an (EVAL-WHEN (:COMPILE-TOPLEVEL) ...)
in the macroexpansion to inform the compiler about the type
predicate, which conforms fully to CLHS DEFCLASS entry.
The type predicate is established in the compile-time environment,
if the defclass happens at top-level.
