Log message:
Update wip/chicken to chicken-4.10.1 (development release).

Changes:
4.10.1
- Runtime system:
  - The calling convention of CPS procedures has been changed to
    use "argument vectors" instead of C calling convention.
  - The C API of C_values(), C_do_apply() and how to invoke CPS
    functions has changed.  The C_procN() macros have disappeared.
    The manual example in "Accessing external objects" for C_values
    has been updated.  See also the "numbers" egg for examples on
    how to support pre- and post-4.10.1 CHICKENs simultaneously.
  - Apply hack is no longer used; the limitation of 128 arguments
    has been lifted for platforms which had no apply hack.
  - Increased the "binary compatibility version" to 8.

Log message:
Update wip/chicken to chicken-4.10.0rc4.

Changes:
The changes since 4.10.0rc1 are as follows:
- SIGBUS, SIGILL and SIGFPE cause proper exceptions instead of panicking
- string-translate* no longer scans beyond string boundaries (CVE-2015-4556)
- A corner case bug in substring-index and substring-index-ci that was
   introduced as part of the fix for CVE-2014-9651 has been fixed.
- chicken.h has been fixed so it does not cause an error in C++ mode.
- create-directory will not skip creation of topmost parent dir in Windows.
- The types.db entries for {read,write}-string read-u8vector have been improved.
- The types.db entries for several SRFI-4 procedures have been fixed.
- The performance of read-u8vector has been improved.
- The "scheme" module now includes an export for the "angle" \ 
procedure.
- normalize-pathname no longer considers ".//foo" as the absolute \ 
"/foo".
- A few small improvements have been made in the manual.

If you're wondering what happened to release candidate 2 and 3, the
rc2 was created but never announced, and rc3 was incorrectly versioned,
so it has been skipped.  Sorry for that, as well :)

Please test this new version on as many platforms as you can, and let
us know if there are any problems with it.  If no problems are found
we can make a 4.10.0 release soon.

  - normalize-pathname has been simplified to avoid adding trailing
     slashes or dots (#1153, thanks to Michele La Monaca and Mario Goulart).

   - write-u8vector has been made more efficient (thanks to Thomas Hintz).

- Unit lolevel:
  - Restore long-lost but still documented "vector-like?" procedure (#983)

- Unit "posix":
  - set-file-position! now allows negative positions for seek/cur (thanks
    to Seth Alves).

    file descriptors (#819, thanks to Michele La Monaca).
  - create-directory on Windows now creates all intermediate
    directories when passed #t as second parameter.

- Runtime system:
  - Removed several deprecated, undocumented parts of the C interface:
    C_zap_strings, C_stack_check, C_retrieve, C_retrieve_proc,
    C_retrieve_symbol_proc, C_i_foreign_number_vector_argumentp,
    C_display_flonum, C_enumerate_symbols
  - Removed several deprecated and undocumented internal procedures:
    ##sys#zap-strings, ##sys#round, ##sys#foreign-number-vector-argument,

    of panicking (thanks to Joerg Wittenberger).

- Module system
  - Allow functor arguments to be optional, with default implementations.
  - Fixed a bug that prevented functors from being instantiated with
     built-in modules.
  - Fixed generation of import libraries for instantiated functors
     (#1149, thanks to Juergen Lorenz).

- Syntax expander
  - define-values, set!-values and letrec-values now support full lambda
    lists as binding forms
  - cond expands correctly when a constant is used in combination with =>
     (thanks to Michele La Monaca)

- C API
  - Removed deprecated C_get_argument[_2] and
    C_get_environment_variable[_2] functions.
  - C_mutate2 has been deprecated in favor of C_mutate
  - chicken.h can be included in C++ programs in strict C++11 mode
     without compiler errors on Linux (thanks to "Izaak").

- Foreign function interface
  - The foreign type specifier "scheme-pointer" now accepts an optional
    C pointer type (thanks to Moritz Heidkamp and Kristian Lein-Mathisen).
  - Type hinting for foreign-primitives now allows returning multiple
    values when no return type has been specified.

- Compiler
  - Fixed an off by one allocation problem in generated C code for (list ...).

- Build system
  - MANDIR was renamed to MAN1DIR and TOPMANDIR was renamed to MANDIR
     in order to comply with standard Makefile practice in UNIX.
  - INCDIR was renamed to CHICKENINCDIR, and now derives from
     INCLUDEDIR, which defaults to $(PREFIX)/include
  - BINDIR, LIBDIR, SHAREDIR, INCLUDEDIR, MANDIR, MAN1DIR, DOCDIR,
     CHICKENINCDIR and CHICKENLIBDIR will now also be taken from
     the environment, if present (like PLATFORM, DESTDIR and PREFIX).

- Tools
  - "csc"
    - On Cygwin, -static now works again (thanks to Michele La Monaca)
  - "chicken-install"
    - When using chicken-install -retrieve, and an error occurs during
       retrieval (or the egg doesn't exist), the egg's directory is
       now properly cleaned up (#1109, thanks to Alex Charlton)
  - "chicken"
    - The -r5rs-syntax option did nothing; this has been fixed.

Log message:
Update to Chicken 4.8.2 snapshot.

Log message:
Update to Chicken 4.8.0.5.

Log message:
Update Chicken wip "development snapshot" package to stable release \ 
4.8.0, while pkgsrc is still in freeze.

Changes since 4.7.0.6:

- Security fixes
  - improved hash table collision resistance and added randomization
    to prevent malicious external causes of collisions.  All SRFI-69
    procedures accept extra arguments to control randomization for
    testing/debugging.
  - Added checks for embedded '\0' characters in strings passed to some
    C functions on a lower level than Chicken's FFI.

- Build system
  - version information has been moved into a separate unit to make the
    build-version shown in the banner and accessible through library
    procedures more accurate, this also speeds up the build on version-
    changes (thanks to Jim Ursetto for contributing this)
  - the build was made more reliable with respect to cross-compilation
    and custom installation names
  - the test-suite is now working on the mingw32 platform (with
    a few tests disabled due to missing functionality)
  - the version and branch of the sources are now properly compiled
    into the core libraries and shown in the "csi" and "chicken"
    version headers

- Compiler
  - Fixed bug in handling of symbols in constant-definitions (thanks to Peter
    Bex)
  - Stricter check for value-part of constant definition (thanks to Kon Lovett)
  - Fixed bug that caused argument-signatures of external definitions to be
    incorrectly modified during optimization (thanks to Peter Bex)
  - Failing constant-folding expressions now produce a compile-time warning
  - Fixed various bugs in the internal type-database (thanks to Kon Lovett and
    Peter Bex)
  - added "-specialize" option and "specialize" declaration \ 
which enables
    optimizations of uses of core library procedures based on type-
    information gathered during flow analysis
  - "-optimize-level 3" and higher now implies "-specialize"
  - added option "-strict-types" and "-emit-type-file"
  - progress-information is now only shown with "-debug p"; the \ 
"-verbose"
    option only shows informational but noncritical messages
  - added optimizations for some library procedures
  - variable propagation for global variable accesses is now done in certain
    situations
  - the algorithmic complexity of the closure-conversion pass has been
    reduced which speeds up compilation noticably for large files
  - the alternative branch in a conditional is dropped when the condition
    is known to be a non-boolean value (suggested by Joerg Wittenberger)
  - implemented numerous fixes and improvements for flow analysis
  - fixed a bug in the compiler that could cause some variable bindings
    to be optimized away in certain situations involving inlining
  - added an experimental optimization called "clustering" (enable
    with the compiler option of the same name)
  - the optimizations done by the compiler are now listed as a comment
    in the generated C file
  - the type-information obtained during flow-analysis ("scrutiny") is 
    now used for performing type-sensitive optimizations of calls to
    most of the core-library procedures
  - deprecated the "constant" declaration specifier
  - "unboxing" optimization has been completely removed - the \ 
implementation
    was unreliable and unmaintainable; the "-unboxing" compiler option will
    still be accepted but will produce a warning
  - Peter Bex contributed an optimization to the analysis pass that 
    greatly reduces compile time for source code containing deeply nested
    lexical bindings
  - procedures that are known to have the value of a core library procedure
    that is a "standard" or "extended binding" will be inlined
  - enhanced line number tracking to get better error messages from
    the scrutinizer.
  - hygiene bugs related to compiler-syntax were fixed.
  - the local flow-analysis was sometimes reporting multiple warnings
    for the same type-conflict.
  - the time/space-complexity of some algorithms used in the compiler
    were reduced resulting in much better compile-times especially
    for large source files.

- Interpreter
  - ",q" leaves the currently active REPL invocation instead of
    terminating the process (as suggested by John Cowan)
  - ",m" properly switches between modules (thanks to Christian Kellermann)

    to Ivan Raikov)
  - Got rid of some warnings in the C runtime system that were triggered on
    the SunPro C compiler (thanks to Joe Python)

efficient and
    have a more consistent argument order than the corresponding
    SRFI-1 procedures

    standards compliant
  - "file-exists?" and "directory-exists?" work now properly \ 
for files

  - fixed bug in implementation of "fifo?"
  - the procedure returned by "condition-predicate" accepts any type
    of argument now
  - blobs have a readable textual representation ("#{...}")
  - "find-files" does not follow symlinks by default (as it did previously)
  - also, the old non-keyword argument signature for "find-files" is not
    supported anymore
  - added "alist-update" ("data-structures" unit)
  - "irregex-replace" returns the original string instead of #f when the
    regex does not match

  - deprecated "none?", "always?" and "never?"
  - library procedures that take ports as arguments now all perform checks
    on port-direction and open/closed state
  - "mutate-procedure" has been renamed to \ 
"mutate-procedure!" - the old
    name is still available but deprecated
  - deprecated C_hash_string and C_hash_string_ci functions in the C API in
    favor of the more secure versions C_u_i_string_hash, C_u_i_string_ci_hash
  - a number of bugs in the irregex regular expression engine have been
    fixed; it has been updated to upstream release 0.8.3

      "CHICKEN_C_LIBRARY_PATH" can now be used to add default include-
      and link-directories to C-compiler invocations
    - "-O5" passed expensive optimization flags to the C compiler which
      could expose C-Compiler bugs, depending on the compiler version
      (thanks to Sven Hartrumpf for pointing this out).
    - "-rpath" is ignored on OS X (thanks to Kon Lovett).
    - Fixed handling of "-output-file" (it was being ignored)
  - "chicken-install"
    - Added option "-override", which allows retrieving extension-
      versions from a file - this may be useful to ensure specific 
      versions of a complete set of eggs are installed
    - Added option "-keep-installed"/"-x" that only installs \ 
explicitly
      named extensions given on the command line, if they are not
      already installed

    renamed in quoted literals (thanks to Matthew Flatt)
  - fixed devious bug in the invocation and generation of transformer
    procedures
  - using normal "lambda" forms as transformers for local or global
    syntax definitions is deprecated - one should use "syntax-rules",
    "er-macro-transformer" or "ir-macro-transformer" from now on

- Runtime system
  - support for re-loading of compiled files has now been completely 
    removed
  - the maximum length of strings is no longer limited to a 24-bit
    number on 64-bit architectures but can be 56 bits.
  - string-comparison handles embedded '\0' characters.
  - numerical predicates handle infinity and NaN correctly.
  - deprecated "[+-]nan", "[+-]inf" and other notations \ 
"accidentally"
    accepted by Chicken due to the underlying C library's strtod() function,
    standardizing on "[+-]nan.0" and "[+-]inf.0" from R6RS \ 
(and soon R7RS),
    when displaying numbers only these forms are generated now.
  - signals are queued to some extent and the interrupt handling has
    been cleaned up somewhat
  - the interpreter handles SIGINT directly - loading the "posix" unit
    is not needed anymore to handle this feature
  - changed default nursery size slightly and fixed a bug that caused
    incorrect (too small) nursery sizes on 64-bit platforms

  - the assembly-language stub routine for the implementation of "apply"
    was broken for Sparc64 systems and has been disabled for this platform
  - signal masks were accidentally reset upon GC for some platforms; use
    sigsetjmp/siglongjmp on BSD, Linux, MacOS X and Haiku
 
- Type system
  - added new type-specifiers "input-port", "output-port", \ 
"(list-of T)" 
    and "(vector-of T)"

represent
    fixed size lists and vectors now
  - added qualified types ("forall"), optionally with type constrains
  - added the "define-type" special form and type-abbreviations
  - added "compiler-typecase", a compile-time typematching form

- Module system
  - Added "interfaces", which are named groups of exports
  - Added "functors", which are parameterized modules

  - New syntax:
    (define-interface NAME EXPORTS)
    (functor (NAME ...) EXPORTS ...)
  - Extended syntax of "module" for aliasing and functor-instantiation
  - the "scheme" module has been integrated into the core library and
    is not installed as a separate import library anymore
