chicken5: update to version 5.3.0

Changelog (taken from https://code.call-cc.org/releases/5.3.0/NEWS):

5.3.0

- Core libraries
  - In (chicken process-context posix), the setters for current-user-id,
    current-effective-user-id and current-group-id now check that the
    new user/group value is a fixnum instead of blindly passing it on
    to the C implementation (which would cause bogus user ids to be set).
    Fixes #1787, thanks to Christopher Brannon.
  - The srfi-17 module now exports the `getter-with-setter` and `setter`
    procedures, not just the set! macro (thanks to Lassi Kortela)
  - Fix hang in chicken-install -update-db on Windows (thanks to Mark
    Fisher for reporting and Jani Hakala for debugging and patch).
  - Fixed an inadvertant error during error reporting in the `numerator`
    and `denominator` procedures when passed non-finite flonums (#1730).
  - Fixed a bug where optimisations for `irregex-match?` would cause
    runtime errors due to the inlined specialisations not being
    fully-expanded (see #1690).
  - Irregex has been updated to upstream 0.9.10, which fixes behaviour
    of irregex-replace/all with positive lookbehind so all matches are
    replaced instead of only the first (reported by Kay Rhodes), and
    a regression regarding replacing empty matches which was introduced
    by the fixes in 0.9.7 (reported by Sandra Snan).  Also, the
    http-url shorthand now allows any top-level domain and the old
    "top-level-domain" now also supports "edu" (fixed by \ 
Sandra Snan).
    Also, a problem was fixed with capturing groups inside a kleene
    star, which could sometimes return incorrect parts of the match.
    Finally, "bol" handling was fixed to handle newlines consistently
    so that multiple matches don't overlap (reported by Sandra Snan).
  - current-milliseconds has been deprecated in favor of the name
    current-process-milliseconds, to avoid confusion due to naming
    of current-milliseconds versus current-seconds, which do something
    quite different.  Also, its definition has been tweaked to
    guarantee that it returns the time since process startup.  On
    Windows, it will now return sane values after 24 days of uptime.
    On UNIX, the values returned will be precise to the millisecond
    instead of rounded down to the nearest second at startup (which
    would result in erratic startup times).
  - The default mode for files created by `file-open' has been changed
    to 0666 (plus whatever change the effective umask applies), rather
    than 0744 (see #1698).
  - Fixed type database entry for "log" with second arg (fixes #1725).
  - Made topological-sort behave better when dependency target is listed
    multiple times by concatenating dependencies (fixes #1185).

- Module system
  - Reexported macros now work when the reexporting module redefines
    identifiers from the original (fixes #1757, reported by Sandra Snan).
  - When using "except" in "import" to omit reexported macros,
    they are really not imported (#1771, reported by Sandra Snan).

- Runtime system
  - Sleeping primordial thread doesn't forget mutations made to
    parameters in interrupt handlers anymore. (See #1638. Fix
    contributed by Sebastien Marie)
  - A feature corresponding to the word size is available
    regardless of the word size (#1693)
  - The default maximum heap size on 64-bit platforms is now the
    theoretical maximum addressable memory size (#1675).  Use -:m
    if you would like to override this at run-time.
  - Deprecated C_(a_i_current_)milliseconds in favor of
    C_(a_i_)current_process_milliseconds to match the Scheme-level
    deprecation of current-milliseconds.
  - Officially deprecated C_pair() in favor of C_a_pair(); it has
    been deprecated for years.
  - At program cleanup, finalizers are only forced when the live
    finalizer count is non-zero
  - The symbol `srfi-87` has been added to the list of built-in
    feature identifiers.
  - Garbage collection algorithm has been changed to reduce thrashing
    when heap is almost full, by growing the heap sooner.  A new -:hf
    option was added to tweak when heap growth should occur.
  - Added `-:R' runtime option to initialize rand() state
    deterministically (should help with #1650 and benchmarking).

- Compiler
  - Statically linked programs using built-in libraries are supported
    again (fixes #1788, a regression from 5.2.0).
  - Avoid re-using argvector when inline rest operations are being
    used in CPS calls (#1703, thanks to Jakob L. Keuze).
  - An `emit-types-file` declaration has been added, which corresponds
    to the compiler flag of the same name (#1644, thanks to Marco Maggi
    for the suggestion).
  - Fixed a bug caused by a bad interaction between two optimizations:
    argvector rest ops would be applied even if a procedure already got
    its rest arg consed at the call site (#1756, thanks to Sandra Snan).

- Build system
  - Fix build with tcc.
  - Fix a few tests on Windows so the suite passes once again.
  - Auto-configure at build time on most platforms. Cross-compilation
    still requires PLATFORM to be set, and it can still be provided
    manually, but it is no longer required in the common case.
  - Fix Linux to MingW cross-compilation (#1768, thanks to Théo Cavignac)
  - The `clean' target for make now also removes build configuration files.
  - The `distclean' target for make has been removed (now `clean' does what
    `distclean' used to do).

- Tools
  - Fix a problem with egg installation scripts on Windows, where the
    platform was not correctly identified, depending on the shell used
    during installation of the core system (thanks again to Mark Fisher
    for reporting and helping in finding the culprit).
  - Fixed a bug in chicken-install (#1744) that would cause
    `Error: (string->number) bad argument type: #!eof` in some cases.
  - If chicken-install has a program prefix/suffix, it now writes to a
    cache directory matching its program name (#1713, thanks to Alice Maz)
  - Fixed bug in chicken-install regarding variable quotation on UNIX-like
    systems which prevented installation into paths with spaces (#1685).
  - Fixed a similar bug in chicken-install for paths with spaces on mingw
    and mingw-msys (#1727, thanks to Josh Helzer for reporting and Vasilij
    Schneidermann for the patch).

- Module system
  - Fixed a memory leak when calling (import) multiple times in a row
    on the same module (#1772; reported by "plugd" on IRC).

chicken: Update to version 5.2.0

Changelog:

5.2.0

- Core libraries
  - Fix `memory-statistics` by returning semi-space bytes and used
    semi-space bytes like the documentation says. Old implementation
    returned full-heap size and (full-heap - used-semi-space).
  - for-each and map now behave consistently in compiled and interpreted
    mode, like in SRFI-1.  They now stop when the shortest list is
    exhausted instead of raising an exception (fixes #1422).
  - There is now a srfi-88 module which contains just the three
    procedures from the (chicken keyword) module defined by the SRFI.
  - A feature identifier named "srfi-88" is now registered.
  - The procedures `record-printer` and `set-record-printer!` and a
    corresponding SRFI-17 setter have been added. These deprecate
    `define-record-printer` which isn't a "real" definition (see #1294).
  - On Windows, `decompose-directory` no longer crashes when a drive
    letter is present in the supplied path string.
  - irregex-replace[/all] have been fixed for empty matches, so they
    will no longer drop characters and ignore the replacement (#1661).
  - Irregex has been updated to upstream 0.9.7, which also improves
    how empty matches are treated in irregex-fold and irregex-split.

- Runtime system
  - Quoted empty keywords like ||: and :|| are now read like prescribed
    by SRFI-88 in the corresponding keyword mode.  Symbols containing
    quoted empty prefixes or suffixes like ||:abc and abc:|| will be
    read correctly as symbols now (fixes #1625, thanks to Andy Bennett).
  - IEEE floating point negative zero is now properly handled: it can
    be read, written and distinguished by eqv? and equal?, but not =
    (fixes #1627, thanks to John Cowan).
  - ##sys#check-exact and its C implementations C_i_check_exact and
    C_i_check_exact_2 have been deprecated (see also #1631).
  - When garbage collector is manually invoked from a finalizer, raise
    an error instead of hanging forever (fixes #1586).
  - define-record-type will now give an error if the constructor
    definition refers to field that's not listed elsewhere (see #1633)
  - Added new -:hu option to set the memory usage low watermark
    percentage at which the heap should be shrunk, and changed the
    calculation to actually reflect this (see #1379).

- Compiler
  - Fixed a bug in lfa2 pass which caused "if" or "cond" \ 
nodes to be
    incorrectly unboxed if the "else" branch had a flonum result type
    (#1624, thanks to Sven Hartrumpf)
  - Inline files no longer refer to unexported foreign stub functions
    (fixes #1440, thanks to "megane").
  - In some cases, rest argument lists do not need to be reified, which
    should make using optional arguments and case-lambda faster (#1623).
  - Values from foreign types which have an argument or return value
    converter are no longer inferred to have the Scheme type which
    corresponds to the raw foreign type, which was incorrect (#1649).

- Module system
  - Trying to export a foreign variable, define-inlined procedure or
    define-constant variable gives a friendly error instead of saying
    the variable doesn't exist (fixes #1346).
  - When modules are registered, they no longer pollute the global
    environment with imports made in that module (fixes #1548)

- Tools
  - The new "-module-registration" options causes module registration
    code to always be included in the program, even when it has also
    been emitted as a separate file (for example with "-J").
  - chicken-install now correctly checks server response code to avoid
    interpreting error response bodies (like 404, 500) as Scheme code.
  - chicken-install now follows HTTP redirects when downloading eggs.
  - chicken-install will now change to the correct drive before
    attempting to change to the egg directory (fixes #1647).

PKGREVISION++

Log message:
Update to 5.1.0

Changelog:
5.1.0

- Core libraries
  - Symbols ending or starting with a colon are now always pipe-quoted
    when written by `write` to ensure they can be read back with a
    different keyword-style setting.
  - Read-write invariance of special symbols starting with #! other
    than #!key, #!rest or #!optional is now preserved (#1572).
  - When using (set-file-position!) on a port, its EOF status will now
    be reset.
  - In (chicken file posix), the values of perm/irgrp, perm/iwgrp,
    perm/ixgrp, perm/iroth, perm/iwoth and perm/ixoth are now correctly
    defined (they were all for "usr"; #1602, thanks to Eric Hoffman).
  - In (chicken file posix), `file-truncate` now accepts also accepts
    port objects, for consistency with other file procedures.
    All such procedures from (chicken file posix) now have the correct
    types in types.db (fixes #1609, thanks to Robert Jensen).
  - Add the system-config-directory and system-cache-directory procedures
    in the chicken.platform module. These procedures follow the XDG
    specification and also give sensible results on Windows.
  - Fix get-environment from (chicken process-context) to raise an
    error when passed #f instead of segfaulting.
  - Qualified symbols (##foo#bar style) are no longer encoded by a
    byte prefix inside the symbol name.  This ensures read-write
    invariance of symbols which start with a low-byte character
    (fixes #1077, except for keywords, which start with NUL bytes).
  - Fix a missing export (list->s64vector) in SRFI-4.

- Runtime system
  - Keywords are now distinct types; they are not a subtype of symbols.
  - Use arc4random on FreeBSD (thanks to Tobias Kortkamp and gahr)
  - Removed the unused, undocumented (and incorrect!) C functions
    C_delete_symbol_table and C_set_symbol_table.
  - Continuations which discard additional values beyond the first no
    longer accept multiple values via direct invocation after being
    captured through `call/cc`, only via `values` (revert of #1390,
    due to #1601)
  - SRFI-4 vector predicates, reference, set and length procedures
    should now be faster in tight loops as they're inlineable (#757).
  - Keywords are now interned in a separate keyword table, not in the
    standard symbol table.  This brings full read-write invariance
    for symbols (they can now also start with NUL bytes).  Keywords
    no longer have plists.  Fixes #1576.
  - Increased the "binary compatibility version" to 11.

- Compiler
  - Restored optimized implementations of =, +, -, /, * and quotient in
    fixnum-arithmetic mode (fixes #1604 mostly; thanks to "chickendan").
  - Added an optimization pass for reducing the amount of boxing of
    intermediate floating point values, enabled by the "-lfa2" compiler
    option.
  - The "lfa2" pass is now enabled at optimization levels 2 or higher.

- Module system
  - When you try to import the module you are currently defining into
    itself, an error will be raised. This prevents an infinite loop in
    the compiler when later trying to import that same module (fixes
    #1506, thanks to Kristian Lein-Mathisen).

- Foreign function interface
  - Improved hygiene in FFI macro expansions, which means you don't
     have to import "scheme" or "(chicken base)" for them to \ 
work.

- Type system
  - It is now possible to quote free variables in type declarations,
     which acts as shorthand for `forall' (thanks to "megane")

- Tools
  - csi now uses (system-config-directory) to find csirc and falls back to
    $HOME/.csirc when needed.
  - chicken-install now uses (system-config-directory) to find a user
    defined setup.defaults file ; it also uses (system-cache-directory)
    for its egg cache directory when the CHICKEN_EGG_CACHE environment
    variable is not defined.

- Egg specifications
  - Allows "cond-expand" and "error" forms in egg \ 
specification files.
  - Add "c-object" and "object" properties to link \ 
separately compiled
     C objects into CHICKEN code.
