changes in sbcl-0.9.13 relative to sbcl-0.9.12:

  * new feature: source path information is generated for macro-expansion
    errors for use in IDE's like Slime (thanks to Helmut Eller)
  * bug fix: calls to the compiler no longer modify *RANDOM-STATE*
  * bug fix: compiler does not loop forever on an invalid type in
    TYPEP.
  * improvement: compilation of most CLOS applications is significantly
    faster
  * optimization: added a limited bytecode compiler for simple toplevel
    forms, speeding up compilation and FASL loading
  * bug fix: the statistical profiler now properly distinguishes anonymous
    functions
