+changes relative to sbcl-1.0.39:
+ * bug fix: Name conflicts between symbols passed as arguments to a
+single call to IMPORT no longer add multiple symbols with the same name
+to the package (detectable via DO-SYMBOLS).
+ * bug fix: support building without the dlshim on darwin x86 and x86-64
+ (lp#533470).
+ * bug fix: TRACE :ENCAPSULATE NIL now works on ppc/linux.
+
+changes in sbcl-1.0.39 relative to sbcl-1.0.38:
+ * bug fix: Backtrace from undefined function on x86 and x86-64 now show
+ the calling frame.
+ * bug fix: linkage-table entries on PPC now no longer overflow their
+ space allocation (potentially causing crashes if they are written out
+ of order).
+ * bug fix: Scrub control stack after scavenging in gencgc on non-x86oid
+ platforms, preventing the GC from seeing stale pointers on the control
+ stack in subsequent GCs (which would, and does, break invariants).
+ * bug fix: 32-bit unicode external formats now work on big-endian systems.
+ * bug fix: Literal characters with code points greater than about 32767
+ now work on PPC UNICODE builds.
+ * bug fix: Any noise left by SSE operations (sqrt and conversions) in the
+ high order bits are explicitly cleared out. In some contrived situations,
+ this could lead to wrong results in mixed real/complex float arithmetic.
+ * bug fix: Fix function/macro redefinition warnings when building with
+ clisp. (lp#576787, thanks to Josh Elsasser)
+ * new platform: experimental support for ppc/openbsd (thanks to Josh
+ Elsasser).
+ * bug fix: Floating-point traps now work on ppc/linux.
+
+changes in sbcl-1.0.38 relative to sbcl-1.0.37:
+ * incompatible change: Thread names are now restricted to SIMPLE-STRINGs
+ like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
+ * deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
