Scheme跨平台编译器

	- added `-ffi-custom" option.
	- easyffi: handles prerprocessor macros nort starting at the first position of a line.
	- posix.scm: added `file-[access|change]-time" and `file-stat" [Suggested by Peter Bex].
	- utils.scm: `make-pathname" didn"t remove the leading "/" from the file component, if not needed.
	- Fixed bug in the generation of an error-messages if non-matching argument-lists of inlined/customized calls
	  had a rest parameter.

	* README, TODO, batch-driver.scm, build.scm, c-backend.scm, c-platform.scm, chicken-entry-points.scm, chicken-highlevel-macros.scm, chicken-more-macros.scm, chicken-setup.scm, chicken.h, chicken.texi, configure.in, csi.scm, easyffi.l, easyffi.scm, eval.scm, extras.scm, library.scm, lolevel.scm, makefile.dj, makefile.vc, pcre.scm, posix.scm, pregexp.scm, psyntax.scm, regex.scm, runtime.c, support.scm, tcp.scm, wwchicken:
	- tcp.scm: added missing #define EINPROGRESS for Windows
	- makefile.vc: still had some occurrences of "graph", where "partition" was needed
	- csc.scm: fixed bug in handling of "-l..." on Windows
	- wwchicken: `stream-cgi" is now in web category, `rgraph" needs `srfi-40"
	- extras.scm: `noop", `atom?"
	- eval.scm: error messages with a single void argument in addition to the message where
	  printed without the argument; `repl-prompt" holds now a procedure instead of a string
	- chicken-setup.scm: errors during loading of a setup-script did not output anything
	- library.scm: added `test-feature?"
	- easyffi: parser accepts `#" everywhere now; illegal characters are shown in error message;
	  user-defined types are heeded when computing classes with full specialization
	- "curried" `define" syntax ("(define ((foo x) y) ...)") is supported
	- `include" preserves line-number counter of reader
	- regex: `grep" uses `string-search" instead of `string-match" [Thanks to Alejandro Cuervo]
	- posix: `set-group-id!", `create-session", `process-group-id" and `set-process-group-id!" [suggested by Peter Bex]
	- lolevel: `pointer=?"
	- new foreign types `symbol" and `number" [The latter was inspired by Daniel B. Faken]
	- csi: changed prompt and added `#INDEX"/`#" read syntax for easier handling of the REPL history
	- eval.scm: reading in a repl swallows any #\newline directly following the input [suggested by Taylor Campbell]
	- chicken-more-macros.scm: `case-lambda" depends on srfi-1 at expansion time (so it"s loaded)
	  [thanks to Michele Simionato]
	- changed the prefix for certain "easy" FFI macros from "__" to "___" to avoid collisions with identifiers
	  in C standard headers

2004-08-05  njbeckford  <njbeckford@gurke>

	* chicken-setup.scm:
	Fixed bug for "chicken-setup xxx.egg".  Previously it would unpack the
	egg and then go into a recursive loop.  Now it unpacks the egg and
	runs the embedded setup script.

2004-08-02  flw  <flw@gurke>

	* TODO, c-backend.scm, chicken-entry-points.scm, chicken.texi, compiler.scm, easyffi.scm, eval.scm, extras.scm, support.scm, wwchicken:
	- fixed instance-ref"s in FFI [Thanks to Petter Egesund]
	- extras: `rassoc"; fixed buf in `alist-ref"
	- wwchicken: added some links; categorized eggs
	- eval: `set-extension-specifier!"

2004-08-01  sven1999  <sven1999@gurke>

2004-07-20  sven1999  <sven1999@gurke>

	* chicken.texi:
	removed @code from 1 @node line (causes crash on second run of tex), increased build number from 43 to 62

	- extras: `read-token"
	- some output routines use faster version of `write-char"
	- compiler: `export" declaration is able to export toplevel variables from psyntax modules
	- chicken-setup: some diagnostic output is suppressed in non-verbose mode
	- wwchicken: fixed a bug related to creating proper timestamps for eggs
	- c-backend.scm: unsafe marker wasn"t generated when no partitioning was selected
	- eval.scm: `load" and include-path resolving ignores directory names
	- visiting files (either explicitly or via `import") does load syntax-extensions, if needed
	- when special core include files (like `chicken-more-macros.scm") are accessed via `use" or
	  `require-extension", then care is taken to load them only once
	- easyffi.l: end of input resets pp-mode
	- `print-error-message" didn"t show location (if provided)
	- Chicken should now work on amd64 platforms [Thanks to Thomas Weidner and Tollef Fog Heen]

	- chicken-setup: unpacks eggs into a temporary directory; host without port didn"t work; addded
	  `-keep" option
	- changed snail-mail address in source file headers
	- easyffi.l: uses `reverse-list->string"
	- srfi-13: `string-contains-ci" wasn"t implemented; `string-contains[-ci]" had off-by-one error
	  [Thanks to Peter Wang]
	- tcp.scm: error messages give location (mostly)
	- tcp.scm: `tcp-connect" doesn"t block other threads [Thanks to Peter Wang]

	- `define-record-type" expanded into code that didn"t allow subsequent exported definitions
	  in psyntax module forms [Thanks to Grzegorz Chrupala]
	- removed some leftover occurrences of `-extra-libs" [Thanks to Sven Hartrumpf]
	- `define-method" expands into a non-definition, which works better with the psyntax module system
	  [Thanks to Grzegorz Chrupala again]
	- ",r" command in csi was broken
	- library: added `memory-statistics"
	- call/cc called with a known lambda is optimized away in case the continuation-variable is never used

	- renamed unit `script-utils" to `utils"
	- csc: handles `-split" properly
	- compiler prefixes identifiers when generating split files

	- some library files were still not up-to-date with respect to the changed declaration syntax for internal
	  procedures (like FFI stubs or trampolines). This caused gcc 3.4 to choke on tcp (and possibly other files
	  that hadn"t been re-translated for longer) [Thanks to Pierre]
	- eval.scm: `syntax-error"
	- the SRFI-22 driver programs (trampolines) have been removed
	- Makefile.am: added dependency for library.c (build.scm)
	- chicken-setup: options `-fetch" and `-install-as-root"
	- `open-output-file": append-mode was completely broken
	- added css stylesheet for HTML version of manual [Thanks to Johannes Groedem]
	- added case for amd64 to chicken.h (doesn"t yet run, though) [Thanks to thomas001]
	- `define-foreign-[type|variable]" didn"t check first argument for being a symbol [thanks to Eric Meritt]
	- added `use" as an alias for `require-extension"
	- `command-line-arguments" filters out runtime options (anything starting with "-:")
	- added another optimizer rule; `thread-specific[-set!]" is inlined in unsafe mode
	- `print[*]" returns 1st argument

2004-06-13  njbeckford  <njbeckford@gurke>

	* hen.el:
	Fixed: char table range must be t, charset, char or vector ... using solution at http://list-archive.xemacs.org/xemacs-beta/200310/msg00407.html

	- posix.scm: patched `file-mkstemp" [Thanks to Johannes Groedem]
	- rcsi has been dumped
	- csi now only uses the library, eval and extras units
	- `extras" has been added to the list of units used by default in compiled code (this means csi
	  and compiled code have basically access to the same set of definitions)
	- csc always links safe libs, providing `-unsafe-libraries" always links with unsafe ones (independent
	  of any other setting) [Thanks to Sven Hartrumpf]
	- chicken-config: removed `-extra-libs" option (`-libs" adds all libraries now)
	- chicken-setup: attempts to handle the "dll" extension transparently in `make" forms [Thanks to T. Kurt Bond]
	- `undefine-macro!" and `macro?" work now with highlevel macros

	- posix.scm: `user-information" returns now either a list or #f
	- `include" accepts any number of arguments [Suggested by Taylor Campbell]
	- library: added `reverse-list->string" (and removed it from srfi-13) and added some minor optimizations
	  to `[##sys#]substring" [Thanks to Sven Hartrumpf]
	- posix: added `file-mkstemp" [Contributed by Johannes Groedem]
