+243: "STYLE-WARNING overenthusiasm for unused variables"
+ (observed from clx compilation)
+ In sbcl-0.7.14, in the presence of the macros
+ (DEFMACRO FOO (X) `(BAR ,X))
+ (DEFMACRO BAR (X) (DECLARE (IGNORABLE X)) 'NIL)
+ somewhat surprising style warnings are emitted for
+ (COMPILE NIL '(LAMBDA (Y) (FOO Y))):
+ ; in: LAMBDA (Y)
+ ; (LAMBDA (Y) (FOO Y))
+ ;
+ ; caught STYLE-WARNING:
+ ; The variable Y is defined but never used.

+244: "optimizing away tests for &KEY args of type declared in DEFKNOWN"
+ (caught by clocc-ansi-test :EXCEPSIT-LEGACY-1050)
+ In sbcl-0.pre8.44, (OPEN "foo" :DIRECTION :INPUT :EXTERNAL-FORMAT 'FOO)
+ succeeds with no error (ignoring the bogus :EXTERNAL-FORMAT argument)
+ apparently because the test is optimized away. The problem doesn't
+ exist in sbcl-0.pre8.19. Deleting the (MEMBER :DEFAULT) declaration
+ for :EXTERNAL-FORMAT in DEFKNOWN OPEN (and LOAD) is a workaround for
+ the problem (and should be removed when the problem is fixed).

+245: bugs in disassembler
+ a. On X86 an immediate operand for IMUL is printed incorrectly.
+ b. On X86 operand size prefix is not recognized.
+
+246: "NTH-VALUE scaling problem"
+ NTH-VALUE's current implementation for constant integers scales in
+ compile-time as O(n^4), as indeed must the optional dispatch
+ mechanism on which it is implemented. While it is unlikely to
+ matter in real user code, it's still unpleasant to observe that
+ (NTH-VALUE 1000 (VALUES-LIST (MAKE-LIST 1001))) takes several hours
+ to compile.

+248: "reporting errors in type specifier syntax"
+ (TYPEP 1 '(SYMBOL NIL)) says something about "unknown type
