+changes in sbcl-1.0.20 relative to 1.0.19:
+ * 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.
+
changes in sbcl-1.0.19 relative to 1.0.18:
+ * new feature: user-customizable variable SB-EXT:*MUFFLED-WARNINGS*;
+ warnings that go otherwise unhandled will be muffled if they are
+ of the type that's the value of this variable.
* optimization: stack allocation is slightly more efficient on x86
and x86-64.
+ * bug fix: DEFSTRUCT forms with user-specified :CONSTRUCTOR options,
+ where a raw slot always is initialized using the initform whose
+ type is not know sufficiently well a compile-time are now compiled
+ correctly. (reported by John Morrison)
* bug fix: compiler no longer makes erronous assumptions in the
presense of non-foldable SATISFIES types.
* bug fix: stack analysis missed cleanups of dynamic-extent
arguments in non-let-converted calls to local functions.
+ * improvements to the Windows port:
+ ** adjusted address spaces for building on both Win32 and
+ Win64. (thanks for John Connors)
* fixed some bugs revealed by Paul Dietz' test suite:
** interval arithmetic during type derivation used inexact integer
to single-float coercions.
