+changes relative to sbcl-1.0.55:
+ * bug fix: fix copy-structure. When copying from stack to heap, garbage
+ could end up in the heap making GC unhappy.
+ (Thanks to James Knight, lp#911027)
+ * enhancements
+ ** SBCL can now be built using Clang.
+ * bug fix: compiler errors when weakening hairy integer types. (lp#913232)
+ * bug fix: don't complain about a too-hairy lexical environment for inlining
+ when the function has never been requested for inlining. (lp#963530)

+changes in sbcl-1.0.55 relative to sbcl-1.0.54:
* enhancements to building SBCL using make.sh:
** --fancy can be specified to enable all supported feature enhancements.
** --with-<feature> and --without-<feature> can be used to specify
** --arch option can be used to specify the architecture to build for.
(Mainly useful for building 32-bit SBCL's on x86-64 hosts, not
full-blows cross-compilation.)
+ * enhancement: extended package prefix syntax <pkgname>::<form-in-package>
+ which allows specifying name of the default interning package for the
+ whole form.
+ * enhancement: when *READ-EVAL* is true, arrays with element type other than
+ T can be printed readably using #.-based syntax. (Thanks to Robert Brown)
+ * enhancement: MAKE-ALIEN signals a storage-condition instead of returning a
+ null alien when malloc() fails. (lp#891268)
+ * enhancement: SB-EXT:PRINT-UNREADABLY restart for PRINT-NOT-READABLE
+ conditions can be conveniently accessed through function with the same
+ name, analogously to CONTINUE.
+ * enhancement: SB-EXT:*SUPPRESS-PRINT-ERRORS* can be used to suppress errors
+ from the printer by type, causing an error marker to be printed instead.
+ (Thanks to Attila Lendvai)
+ * enhancement: BACKTRACE and DESCRIBE now bind *PRINT-CIRCLE* to T, and
+ generally behave better when errors occur during printing.
+ * enhancement: the test runner now takes a --report-skipped-tests argument
+ to report the individual tests skipped as well as the number of skipped
+ tests.
+ * enhancement: undefined functions now appear in backtraces as ("undefined
+ function") instead of ("bogus stack frame") on x86oids.
+ * enhancement: detected deadlocks no longer cause stderr to be spammed, and
+ deadlock errors are reported in an easier-to-decipher manner.
+ * enhancement: DESCRIBE on type designators reports the expansion in more
+ cases.
+ * enhancement: SBCL now provides either an explicit :BIG-ENDIAN or
+ :LITTLE-ENDIAN in *FEATURES*, instead of :BIG-ENDIAN being implied by lack
+ of the :LITTLE-ENDIAN feature. (Thanks to Luís Oliveira, lp#901661)
+ * enhancement: better disassembly of segment-prefixes on x86 and other
+ instruction prefixes (e.g. LOCK) on x86 and x86-64.
+ * optimization: FIND and POSITION on bit-vectors are orders of magnitude
+ faster (assuming KEY and TEST are not used, or are sufficiently trivial.)
+ * optimization: SUBSEQ on vectors of unknown element type is substantially
+ faster. (lp#902537)
+ * optimization: specialized arrays with non-zero :INITIAL-ELEMENT can
+ be stack-allocated. (lp#902351)
* optimization: the compiler is smarter about representation selection for
floating point constants used in full calls.
+ * optimization: the compiler no longer refuses to coerce large fixnums to
+ single floats inline, except on x86 where this limitation is still
+ necessary.
* bug fix: deadlock detection could report the same deadlock twice, for
two different threads. Now a single deadlock is reported exactly once.
* bug fix: interval-arithmetic division during type derivation did not
* bug fix: condition slot accessors no longer cause undefined function
style-warnings when used in the :REPORT clause of the DEFINE-CONDITION
form that defines them. (lp#896379)
+ * bug fix: DEFGENERIC warns about unsupported declarations, as specified
+ by ANSI. (lp#894202)
+ * bug fix: SUBTYPEP tests involving forward-referenced classes no longer
+ bogusly report NIL, T.
+ * bug fix: bogus style-warnings for DEFMETHOD forms that both declared some
+ required arguments ignored and performed assignments to others.
+ (lp#898331)
+ * bug fix: *EVALUATOR-MODE* :COMPILE treated (LET () ...) identically
+ to (LOCALLY ...) leading to internally inconsistent toplevel-formness.
+ * bug fix: non-toplevel DEFSTRUCT signaled a style warning for unknown type.
+ * bug fix: redefining a function whose previous definition contained an
+ unknown type no longer causes a style-warning. (lp#806243)
+ * bug fix: undefined functions now appear in backtraces as ("undefined
+ function") instead of ("bogus stack frame") on non-x86oids.
+ * bug fix: backtraces are no longer cut off at ("undefined function") when
+ called under certain circumstances (involving a caller-allocated stack
+ frame) on PPC.
+ * bug fix: RUN-PROGRAM leaked a file-descriptor per call on non-Windows
+ systems. (regression since 1.0.53)
+ * bug fix: GC deadlocks from dladdr() on certain platforms.
+ * bug fix: broken standard streams no longer automatically cause recursive
+ errors on debugger entry.
+ * bug fix: build ignored --dynamic-space-size=<size> argument to make.sh
+ (regression since 1.0.53)
+ * bug fix: attempts to stack allocate a required argument to a function with
+ an external entry point caused compiler-errors.
+ * bug fix: compiler notes for failed stack allocation for a function argument
+ no longer claim to be unable to stack allocate the function.
+ * bug fix: COERCE now signals a type-error on several coercions to
+ subtypes of CHARACTER that are forbidden according to ANSI. (lp#841312)
+ * bug fix: missing failure-to-stack-allocate compiler notes for some
+ forms of MAKE-ARRAY with dynamic-extent. (lp#902351)
+ * bug fix: some of the compile-time side-effects of DEFCLASS were not caught
+ by package locks.
