changes in sbcl-2.0.0 relative to sbcl-1.5.9:

  * minor incompatible change: heap relocation now works on Windows.  Since
    this feature now works on all platforms, it is enabled unconditionally and
    the :RELOCATABLE-HEAP symbol no longer appears on *FEATURES* in any
    builds.  (Thanks to Luís Borges de Oliveira)
  * enhancement: malformed type specifiers and occurrences of deprecated types
    in :TYPE initargs of DEFCLASS and DEFINE-CONDITION slot specifications
    are detected and result in compile-time errors and warnings respectively.
  * enhancement: parallel contrib building, controlled by SBCL_MAKE_JOBS=-jX
    the same as for the C runtime.
  * bug fix: add a walker template for WITH-SOURCE-FORM.
  * bug fix: start the summary of a compilation unit on a fresh line.  (Thanks
    to Zach Beane)
  * bug fix: on Windows, PARSE-NATIVE-NAMESTRING produces an absolute
    directory when parsing a bare drive name and :AS-DIRECTORY is specified.
    (Thanks to Luís Borges de Oliveira)
  * bug fix: on RISCV, the runtime is linked with libz if the core compression
    feature is requested.  (Thanks to Andreas Schwab)
  * bug fix: ADJOIN using an EQL test and a KEY function only transforms into
    an EQ test if the key function returns values for which EQ and EQL are
    guaranteed to be the same.
  * optimizations:
    ** the instruction sequence for multiple-value calls is more
       efficient on x86-64.
    ** the direction flag is now unused on x86 and x86-64 when handling
       an unknown number of return values.  (Thanks to Fanael Linithien)
    ** the x86-64 backend is better able to use memory operands for arithmetic
       operations.
    ** compilation of TYPECASE to a jump table is enabled when all the types
       being tested are frozen.
    ** compilation of CASE and ECASE into a jump table has been implemented on
       32- and 64-bit powerpc platforms.
    ** the implementation of Unicode normalization has been sped up.
    ** pretty-printing dispatch on conses is faster, particularly with the
       standard pretty-print dispatch table.  Deeply-nested forms should also
       pretty-print faster.
