+changes in sbcl-1.0.20 relative to 1.0.19:
+ * minor incompatible change: OPTIMIZE qualities
+ SB-C::STACK-ALLOCATE-DYNAMIC-EXTENT, SB-C::STACK-ALLOCATE-VECTOR,
+ and SB-C::STACK-ALLOCATE-VALUE-CELLS no longer exist. See documentation
+ and SB-EXT:*STACK-ALLOCATE-DYNAMIC-EXTENT* for details.
+ * optimization: ASSOC-IF, ASSOC-IF-NOT, MEMBER-IF, MEMBER-IF-NOT,
+ RASSOC, RASSOC-IF, and RASSOC-IF-NOT are now equally efficient
+ as ASSOC and MEMEBER.
+ * optimization: runtime lookup of function definitions can be
+ elided in more cases, eg: (let ((x 'foo)) (funcall foo)).
+ * optimization: compiler is able to derive the return type of
+ (AREF (THE STRING X) Y) as being CHARACTER.
+ * bug fix: fixed #427: unused local aliens no longer cause compiler
+ breakage. (reported by Stelian Ionescu, Andy Hefner and Stanislaw
+ Halik)
+ * bug fix: non-local exit from a WITH-ALIEN form no longer causes
+ alien-stack leakage. (reported by Andy Hefner)
+ * bug fix: PROGV signals an error when an attempt to violate declared
+ type of a variable or bind a constant is made.
+ * bug fix: SET signals an error when an attempt to violate declared
+ type of a variable is made.
+ * bug fix: restart computation during the execution of a restart
+ test function no longer causes infinite recursion. (reported by
+ Michael Weber)
+ * bug fix: calling SB-COVER:REPORT with a non-directory pathname now
+ signals an error. (thanks to Pierre Mai)
+ * bug fix: EXPORT left symbol unexported in conflict situations.
+ (thanks to Michael Weber)
+ * bug fix: correctly handle name conflicts involving CL:NIL.
+ (thanks to Michael Weber)
+ * bug fix: RESOLVE-CONFLICT restart for name conflicts handles
+ conflicts arising from USEing package with conflicting symbols
+ correctly. (thanks to Michael Weber)
