    (for simple-enough type specifications)
  * Added structure argument type checking in structure slot
    accessor functions
  * Make GENSYM thread-safe
  * Various performance fixes found by running the raytracer
    from http://www.ffconsultancy.com/languages/ray_tracer/benchmark.html

    debugging (Tobias Rittweiler)

    Backtrace functionality been moved from EXT:BACKTRACE-AS-LIST to
    SYS:BACKTRACE to mark this changes.  The methods SYS:FRAME-TO-STRING
    and SYS:FRAME-TO-LIST can be used to inspect the new
    LISP_STACK_FRAME and JAVA_STACK_FRAME objects

==============
(5 Apr, 2009)
svn://common-lisp.net/project/armedbear/svn/tags/0.14.1/abcl

 Summary of changes:

 -------------------
  * Increased clarity on licensing (Classpath exception
     mentioned in COPYING, removed LICENSE)
  * Resolved infinite recursion on TRACEing the compiler
  * Changes on the lisp based build system for parity with Ant
  * Fixed interpreter creation in Java Scripting
  * libabcl.so no longer created; it was solely about installing
     a SIGINT handler. Libraries should not do that.

  * fixed special bindings restores in compiled code for
     MULTIPLE-VALUE-BIND/LET/LET*/PROGV and function bodies

     (fixes RESTART-CASE ANSI failures)
  * fix macroexpansion in the precompiler
  * Fixnum and Bignum now use a static factory method;
      constructors are now private -> increases chances of numbers
      being EQ
  * Code cleanup in EXPT to fix (EXPT <any-number> <Bignum>)
