Log message:
Update to CHICKEN 4.10.0

This is mostly a bugfix release, containing quite a lot of accumulated
bug fixes but relatively few new features.  Nevertheless, there are a
great many changes in this release since 4.9.0.  It has three security
bugfixes: for CVE-2014-6310, CVE-2014-9651 and CVE-2015-4556.

Another important security-related cleanup/improvement is related to path
expansion: many file procedures in CHICKEN used to automatically and
implicitly convert paths containing tilde ("~") characters to $HOME,
and expand shell variables.  This behaviour was deprecated in 4.9.0,
and has now been removed, in favor of the "pathname-expand" egg.

A few of the build variables have been renamed, so if you have a custom
build script, please review the NEWS file carefully.

Other notable changes:

* The performance of reading and writing SRFI-4 u8vectors has been
   substantially improved.
* Various bugs in the functors implementation have been fixed, making
   them better usable.
* chicken.h can once more be correctly compiled with a C++ compiler.
* The -r5rs-syntax flag has been fixed to enforce r5rs syntax.

Log message:
Update to Chicken 4.9.0.1
Tests now work without installing package first.

Changes since previous package:

4.9.0.1

- Runtime library
  - C_MINOR_VERSION changed to 9; feature identifier chicken-4.8 => chicken-4.9

4.9.0

- Security fixes
  - CVE-2014-3776: read-u8vector! no longer reads beyond its buffer when
    length is #f (thanks to Seth Alves).
  - CVE-2013-4385: read-string! no longer reads beyond its buffer when
    length is #f.
  - CVE-2013-1874: ./.csirc is no longer loaded from the current directory
    upon startup of csi, which could lead to untrusted code execution.
    (thanks to Florian Zumbiehl)
  - CVE-2013-2024: On *nix, the qs procedure now single-quotes everything
    instead of relying on a blacklist of shell characters to be escaped.
    On Windows, it properly duplicates double-quote characters.  (thanks
    to Florian Zumbiehl)
  - CVE-2013-2075: Use POSIX poll() in other places where select() was
    still being used.  (thanks to Florian Zumbiehl and Joerg Wittenberger)
  - CVE-2012-6122: Use POSIX poll() on systems where available.  This avoids a
    design flaw in select(); it supports no more than FD_SETSIZE descriptors.

- Core libraries
  - Fix subvector when the TO optional argument equals the given vector
    length (#1097)
  - Unit extras now implicitly depends on ports.  ports no longer
     implicitly depends on extras.  This may break programs which don't
     use modules and forgot to require ports but use procedures from it.
  - Support has been added for the space-safe R7RS macro "delay-force".
  - Export file-type from the posix unit (thanks to Alan Post).
  - SRFI-4 s8vectors now work correctly in compiled code on PowerPC and ARM.
  - thread-join! now works correctly even if the waiting thread was
     prematurely woken up by a signal.
  - unsetenv has been fixed on Windows.
  - The process procedure has been fixed on Windows.
  - Nonblocking behaviour on sockets has been fixed on Windows.
  - Possible race condition while handling TCP errors has been fixed.
  - The posix unit will no longer hang upon any error in Windows.
  - resize-vector no longer crashes when reducing the size of the vector.
  - Distinct types for boolean true and false have been added to the
    scrutinizer.
  - Fixed bugs in string-trim-right, string-index-right and
    string-skip-right, from SRFI-13
  - read-line no longer returns trailing CRs in rare cases on TCP ports (#568)
  - write and pp now correctly use escape sequences for control characters
     (thanks to Florian Zumbiehl)
  - posix: memory-mapped file support for Windows (thanks to "rivo")
  - posix: find-file's test argument now also accepts SRE forms.
  - numerator and denominator now accept inexact numbers, as per R5RS
    (reported by John Cowan).
  - Implicit $VAR- and ~-expansion in pathnames have been deprecated (#1001)
  - Fixed EINTR handling in process-wait and when reading from file ports.
  - Irregex is updated to 0.9.2, which includes bugfixes and faster submatches.
  - Compile-time expansions for "[sf]printf" are slightly more efficient.
  - Removed the deprecated "always?", "never?", \ 
"shuffle" and "none?" procedures.
  - Fixed problem "make-pathname" that returned an absolute path if given
    a relative one without a directory argument.
  - The implementation of promises has been made more efficient.
  - Removed the deprecated "c-runtime", "null-pointer?" and \ 
"pointer-offset"
    procedures.
  - The deprecated alias "mutate-procedure" for \ 
"mutate-procedure!" has
    been removed.
  - On 64-bit systems the feature identifier "64bit" is registered.
  - "process-fork" accepts an optional argument that specifies
    wether other threads should be terminated in the child process.
  - The "signal/bus" signal identifier was missing.
  - Added setter-procedure for "signal-mask".
  - Added "recursive-hash-max-length" and \ 
"recursive-hash-max-depth"
    parameters (srfi-69).

- Platform support
  - CHICKEN can now be built on AIX (contributed by Erik Falor)
  - CHICKEN can now be built on GNU Hurd (contributed by Christian Kellermann)
  - Basic support has been added for building Android and iOS binaries (see
    the "README" file for caveats and pitfalls) (contributed by Felix \ 
Winkelmann
    from bevuta IT GmbH)
  - Added support for 64-bit Windows (consult the "README" file for more
    information).

- Runtime system
  - finalizers on constants are ignored in compiled code because compiled
    constants are never GCed (before, the finalizer would be incorrectly
    invoked after the first GC).  (Reported by "Pluijzer")
  - The call trace buffer is now also resizable at runtime via \ 
##sys#resize-trace-buffer.
  - C_zap_strings and ##sys#zap-strings (undocumented) have been deprecated.
  - Special events in poll() are now handled, avoiding hangs in threaded apps.
  - When invoking procedures with many rest arguments directly (not via APPLY),
    raise an error when argument count limit was reached instead of crashing.
  - When the maximum allowed heap size is reached, panic instead of crashing.
  - The code generated for mutating data destructively is partially inlined
    and thus slightly more efficient.
  - Fixed incorrect code in the foreign argument conversion for
    "unsigned-integer64" (#955).  For unsigned-integer, integer64 and
    unsigned-integer64, disallow floating-point numbers.  Fix behavior
    on 32-bit systems.
  - On systems that provide sigprocmask(2), segmentation violations, illegal
    instruction signals, bus errors and floating-point exceptions are now caught
    and trigger normal error-processing (including a backtrace). The handling
    of these so called "serious" signals can be disabled by passing the
    "-:S" runtime option to executables.
  - Reclamation of unused interned symbols (enabled with the "-:w" \ 
runtime option)
    works much better now.

- Build system
  - The tests can now be run without having to first install CHICKEN.
  - Fixed a dependency problem that made it impossible to build the distribution
    tarball on Windows with the mingw compiler.
  - Increased the "binary compatibility version" to 7.

- Tools
  - "csc"
    - "-z origin" is now passed as a linker option on FreeBSD when
      compiling for deployment (thanks to Jules Altfas & Vitaly Magerya)
    - "-deploy" works now on FreeBSD (thanks to Jules Altfas and
      Vitaly Magerya), OpenBSD and NetBSD (see README for NetBSD).
    - added "-oi"/"-ot" options as alternatives to \ 
"-emit-inline-file"
       and "-emit-type-file", respectively; "-n" has been \ 
deprecated.
    - .c/.o files are no longer overwritten when they have the same basename
      as a Scheme source file (i.e. "csc foo.scm foo.c -o foo" works now).
  - "chicken-install"
    - "-deploy" now correctly installs dependencies of
      deployed eggs under the deployment directory instead of globally.
    - Full URI syntax is now supported for proxy environment variables
      (thanks to Michele La Monaca)
  - "chicken-status"
    - Added -eggs command line option to list installed eggs
  - misc
    - Removed the deprecated "-v" options (use "-version" \ 
instead) in various
      core programs.
    - The runtime linker path for compiled executables was not set correctly
      on FreeBSD systems.  This has now been fixed.
    - Removed the deprecated "make" and "make/proc" facility \ 
from the
      "setup-api" module; also removed the deprecated \ 
"required-extension-version"
      and "required-chicken-version" procedures.

- Syntax
  - Added the aliases "&optional" and "&rest" as \ 
alternatives to "#!optional"
    and "#!rest" in type-declarations (suggested by Joerg Wittenberger).
  - Vectors, SRFI-4 number vectors and blobs are now self-evaluating for
     R7RS compatibility.  Being literal constants, they are implicitly quoted.
  - For R7RS compatibility, named character literals #\escape and #\null are
     supported as aliases for #\esc and #\nul.  WRITE will output R7RS names.
  - The CASE form accepts => proc syntax, like COND (as specified by R7RS).
  - letrec* was added for R7RS compatibility.  Plain letrec no longer behaves
    like letrec*.

- Compiler
  - the "inline" declaration does not force inlining anymore as recursive
    inlining could lead to non-termination of the compiler (thanks to
    Andrei Barbu).
  - Type-analysis ("scrutiny") is enabled by default now, unless
    "-optimize-level 0" or "-no-usual-integrations" is given.
  - The "-scrutinize" compiler option has been deprecated.
  - A new lightweight flow-analysis pass ("lfa2") has been added.
    Enable by passing the "-lfa2" option to the compiler.
  - The deprecated options "-disable-warning", \ 
"-heap-growth", "-heap-shrinkage"
    and "-heap-initial-size" have been removed.
  - Removed the deprecated "constant" declaration.
  - Removed the deprecated "-lambda-lift" and "-unboxing" \ 
compiler options.
  - Removed the deprecated "-V" compiler option.
  - Generated names for formal parameters of foreign functions are slightly
    more informative.
  - Unused references to variables that name intrinsics can be removed.
  - In the flow-analysis pass, matching of combinations of \ 
"list"/"list-of" and
    "or" types with has been made more reliable.
  - Fixed various bugs in the type database.

- Syntax expander
  - added "require-extension-for-syntax" and "use-for-syntax".
  - Extended syntactic definitions are now available by default in all
    evaluated code, particularly in code evaluated at runtime in compiled
    applications.
  - Removed the deprecated variant "(define-compiler-syntax (NAME . LLIST) \ 
BODY ...)"
    of "define-compiler-syntax".

- C API
  - Deprecated C_get_argument[_2] and C_get_environment_variable[_2] functions.
  - Removed the deprecated "__byte_vector" type.

Update to Chicken 4.8.0.5
Requested by Peter Bex.

4.8.0.5

- Security fixes
  - CVE-2013-4385: read-string! no longer reads beyond its buffer when
    length is #f.
  - poll() is also used on cygwin by enabling the fix for CVE-2012-6122
  - file-creation-mode now passes a valid value to umask when its argument
    is omitted.  (Also ensure it always returns the old umask value.)
  - Fix a data corruption problem in list->queue.

- Core libraries
  - read-string! behaves correctly in presence of EOF.
  - Several subtle problems in the reader in the presence of EOF are fixed.
  - Use poll() instead of select() on cygwin.

- Runtime
  - Fix an issue on initial seed of the random number generator.

4.8.0.4

- Runtime
  - Ensure correct type is used for sigsetjmp(3) buffer.  This fixes,
    for example, a bus error in 32-bit OS X builds (#1021).

- Core libraries
  - Export file-type from the posix unit.

- Build system
  - Use inexact comparison for flonum tests, as there is sometimes a
    miniscule difference between trig functions computed by libc and
    those precalculated by gcc.

Log message:
Update to Chicken 4.8.0.
From Peter Bex via pkgsrc-wip.

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)

- Core libraries

  - The printer now does a better job at escaping certain single-character
    symbol names
  - Unit "lolevel"
    - deprecated "null-pointer" and "null-pointer?"
  - Disabled "-setup-mode" when compiling extensions for deployment (thanks
    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)
  - added "foldl" and "foldr" procedures, which are more \ 
efficient and
    have a more consistent argument order than the corresponding
    SRFI-1 procedures
  - "shuffle" has been deprecated
  - added "queue-length"
  - "queue->list" allocates and returns a fresh list now

    standards compliant
  - "file-exists?" and "directory-exists?" work now properly \ 
for files
    > 2GB (EOVERFLOW handling in stat(3) system call)

  - 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
  - irregex "real" built-in utility pattern now accepts a leading sign
  - added "change-directory*" ("posix" unit)
  - number parsing has been made more reliable and standards compliant
  - 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
  - the "make" facility of the "setup-api" module has been \ 
deprecated,
    please use the "make" extension when your egg requires this during
    setup.

- Core tools
  - "csc"
    - The environment-variables "CHICKEN_C_INCLUDE_PATH" and
      "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
    - Added option "-list" that lists all extensions available
    - Added option "-csi" to specify what interpreter should be used
      to execute the setup-script of an installed extension
    - Added option "-scan" that scans a local directory for the highest
      available extension versions available
    - Added option "-reinstall" that reinstalls all currently installed
      eggs, keeping their versions, if possible
    - Fixed bug with "chicken-install -test" when multiple extensions where
      given on the command line (thanks to Kon Lovett)
    - installing subdirectories works now on Windows.
    - fixed handling of "-force" when a "chicken" dependency \ 
version did
      not match
    - added new option "-show-foreign-depends" which lists foreign egg
      dependencies (if available)
    - added new option "-show-depends" which lists egg dependencies
    - added support for "or"-dependencies where a dependency is considered
      installed if one of a set of candidates is available
  - "chicken-profile"
    - fixed some bugs in the profiler and the runtime support code for
      profiling (thanks to Sven Hartrumpf)
  - "chicken-status"
    - Added option "-list" that dumps versions of installed extensions
      in a format suitable for "chicken-install -override ..."
    - the "pattern" argument is now actually treated as a pattern and not
      as a regex

- Core syntax
  - "assert" shows the line number of the form when a second argument
    is not given or is a literal string
  - "parameterize" now correctly omits invoking the guard procedure when
    the old value is restored (thanks to Joo ChurlSoo)
  - added ":", "the" and "assume" syntax for \ 
declaring types
  - added "define-specialization" form to declare type-driven procedure
    call rewrites in compiled code

- Syntax expander
  - Fixed a bug that caused imported identifiers to leak into the
    macroexpansion/compile-time environment (reported by Christian Kellermann)
  - Peter Bex fixed a bug that caused bound variables to be incorrectly
    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
  - deprecated the compiler option "-heap-initial-size", \ 
"-heap-growth"
    and "-heap-shrinkage"
  - 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)"
  - the type-specifiers "(vector T ...)" and "(list 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
  - Modules can now be aliased
  - 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
  - added core module "r4rs" containing only bindings for R4RS identifiers
  - added core module alias "r5rs" for "scheme" module
  - added "module-environment" which returns an evaluation environment
    for the bindings of a module
  - fixed bugs related to using "export"/"reexport" in \ 
combination with
    wildcard ("*") module export lists (thanks to "megane")

- Foreign function interface
  - locatives are allowed as arguments declared "c-pointer"
