Scheme跨平台编译器

	- format, library: uses `reverse-list->string"

2004-05-27  catfive  <catfive@gurke>

	* wwchicken:
	- fixed wwchicken manual links for compiler and interpreter command-line format

2004-05-26  flw  <flw@gurke>

	* support.scm, wwchicken, runtime.c, posix.scm, lolevel.scm, makefile.vc, optimizer.scm, hen.el, library.scm, easyffi.scm, eval.scm, csc.scm.in, configure.in, c-platform.scm, chicken-setup.scm, chicken.h, chicken.texi, compiler.scm, README, TODO, build.scm:
	- makefile.vc: csc.scm.in is copied into csc.scm (or csc.scm wouldn"t be found)
	- eval.scm: `set!" allows assignments to keywords [Thanks to Mikael]
	- support.scm, optimizer.scm: inlined lambdas with empty rest list generated invalid code [Thanks Daniel B. Faken]
	- chicken-setup: doesn"t assume ".so" anymore for compiled extensions, `install-extension" silently
	  handles ".so" extension on Windows [Thanks to T. Kurt Bond]
	- library.scm: the third argument to `substring" is now optional
	- csc.scm.in: `-l..." is passed to linker
	- csc: .i files are passed to swig and passed on to chicken or the C compiler; -swig passes options to SWIG directly
	- hen.el: added a few kewords for highlighting
	- runtime.c: removed C_alloc_in_heap, since the continuation can not be saved and will be invalid if GC should occur
	- compiler: rewriting rules for `string-append" and `substring" in unsafe mode; removed some unneeded variable
	  initialisations from compiler.scm
	- added `custom-declare" declaration and processing of `.csc" files to compiler/csc for doing weird post-compilation
	  stuff...
	- easyffi: `typedef ... *ID" is allowed
	- posix: `user-information" returns 7 * #f, if the user can"t be found [Thanks to Peter Wang]

2004-05-20  flw  <flw@gurke>

	* eval.scm, configure.in, build.scm, chicken-config.in, chicken.texi, README, TODO, Makefile.am:
	- eval.scm: usage of the CHICKEN_REPOSITORY variable for setting the repository-directory was broken
	  [Thanks to Peter Wang]
	- removed csc.scm from distro-tarball [Thanks to Daniel B. Faken]
	- chicken-config used `-Wl,-R" on Mac OS X, which is wrong [Thanks to Houman Zolfaghari]
	- eval.scm: `require" didn"t check current directory [Thanks to Alain Mellan]

2004-05-19  flw  <flw@gurke>

	* wwchicken, README, chicken-default-entry-points.scm, chicken-setup.scm, chicken.h, chicken.texi, compiler.scm, csi.scm, extras.scm, hen.el, runtime.c:
	- chicken-setup: `-program-path" does not influence path to chicken tools
	- runtime.c: added `CHICKEN_is_running()"
	- extras.scm: fixed bug in `write-string" [Thanks to Alejandro Forero Cuervo]
	- csi.scm: fixed wrong implementation of `##csi#symbols-matching" [Thanks to Linh Dang]

	- warnings flush output
	- added CHICKEN_global_... API
	- compiler: `require-extension" warns if extension is not currently installed

	- easyffi.scm: added `destructor_name" and `exception_handler" pseudo declarations
	- tinyclos.scm: result-handling of type `(instance ...)" was broken for returned NULL pointers

	- added missing documentation for `export' declaration [Thanks to Terence Brannon]
	- fixed easyffi parser bug that caused preprocessor-state not to be cleared [Thanks to Feanor]
	- removed line-number output in ffi-parser errors (which was incorrect anyway)
	- keyword processing uses internal version of `get-keyword', and keyword-lookup is a bit faster
	- changed default keyword-style to suffix
	- chicken-format-profile.bat was built incorrectly
	- rcsi still has access to all non-standard syntax
	- C syntax checker didn't handle preprocessor commands properly in certain situations
	- csc: only links with unsafe libs in benchmark-mode or with `-unsafe-libraries'
	- Fixed some typos in the documentation [Thanks to z0d and Kim Liu]
	- C syntax-checks for `foreign-declare' declarations checked each string separatly (which was wrong)

	- Windows batch files are properly generated (without "#!..." line)
	- chicken-setup: added `-registry' option

	- the reader accepts symbols starting with `#%' and `#!', `#! ...' is only treated as commment
	  when used in the interpreter and it appears on the first line
	- batch-driver: erroneously added `use' declaration for lolevel unit, when compiling she-bang scripts

	- removed URL stuff again
	- moved FFI macros into separate include file (`chicken-ffi-macros.scm')
