Log Message:
Update to Chicken Scheme
Requested by Aleksej Lebedev in private mail.

Changes since 4.7.0:

The stability (-st) branch is now the official branch for point
releases, so the -st suffix has been retired.

- Security fixes
  - on 64-bit machines the "random" procedure no longer truncates result
    values (which caused very nonrandom results for very large values).
    Note that random shouldn't be used for security-critical code.
- Core libraries
  - tcp-connect now closes socket on connection timeout
    [thanks to Jorg Wittenberger].
  - Ensure srfi-13 string comparison returns a boolean, fix bugs in
    xsubstring and string-xcopy!, and add a test suite.
  - Fix off-by-one error in pending finalizer code which could lead to crash.
  - Exceptions signalled by code that executes in finalizers will now
    be caught and do not propagate upwards into arbitrary user code.

- Build system
  - LLVM gcc and clang can now be used to compile the system.  Previously,
    building with LLVM produced binaries that would hang and use 100% CPU.
    Fixes compatibility with OS X 10.6 and later.
- Core libraries
  - symbols with a single-char print-name were not always properly escaped
    when printed readably (#772)

- Core libraries
  - "with-input-from-file", "with-output-to-file", "with-input-from-pipe" and
    "with-output-to-pipe" now properly restore the standard input/output
    ports in case the body thunk escapes
- Build system
  - Fixes for port tests
  - C_TARGET_INCLUDE_HOME fix for cygwin

- Core libraries
  - fixed bug in reading of octal escape in string literal
- Compiler
  - fixed erroneous optimization of toplevel assignments in the presence
    of conditionals (found by Paul Colby and Mario Domenench Goulart).
    For example, this had printed "undefined" and now prints "good":
      (define A #t)
      (define B 'undefined)
      (if A
          (set! B 'good)
          (set! B 'bad))
      (print B)

- Core libraries
  - port-procedures now check correctly for argument-ports being open
    (thanks to Peter Bex)
  - fixed irregex overlapping charsets problem (#636)
- Runtime system
  - fixed handling of "inf" floating-point predicate for Solaris
    (thanks to Claude Marinier)
- Core tools
  - "chicken-profile"
    - fixed broken percentage calculation (thanks to "megane")
- Compiler
  - the "-uses" option handles whitespace in unit lists given on the
    command line (thanks to Santosh Rajan)

- Build system
  - The default target library name for an installation configured for cross-
    compilation is now "libchicken" and independent on any particular
    setting of PROGRAM_PREFIX/PROGRAM_SUFFIX (thanks to Otavio Salvador)
- Compiler
  - Fixed incorrect optimization rules for some fp-rounding and fixnum operators
  - Unused arguments in callback wrappers were incorrectly optimized away (#584)
- Core libraries
  - Fixed bugs in "make-pathname" and "normalize-pathname" (thanks to Jim 
  - The reader is now more consistent when parsing symbol- and keyword names
    that are fully or partially escaped (thanks to Kon Lovett)
  - Fixed a bug in the Windows implementation of "file-type" (thanks to
    Jim Ursetto)
  - Fixed a bug in the implementation of "current-milliseconds" that could
    result in integer-overflow
  - Fixed an incorrect type-check in "list-ref" (thanks to Sven Hartrumpf)
  - Fixed bug in "string->number" that caused out-of-range characters to
    be accepted for base > 10 (thanks to Jim Ursetto)
- Foreign function interface
  - "int32" was not properly detected as a valid foreign type (thanks
    to Jim Ursetto)
- Syntax expander
  - Fixed a bug in the processing of extended lambda-lists (thanks to Peter Bex)
