[cola:10432] STklos 0.80 - a Scheme compiler/interpreter

This is an announce for the 0.80 release of STklos.

STklos is a free Scheme System (nearly) conform to R5RS. The aim of this
implementation is to be fast as well as light. The implementation is
based on an ad-hoc Virtual Machine. STklos can also be compiled as a
library, so that one can easily embeds it in an application.

The salient points of STklos are:

* efficient and powerful object system based on CLOS providing
- Multiple Inheritance,
- Generic Functions,
- Multi-methods
- an efficient MOP (Meta Object Protocol)
* a simple to use module system
* implements the full tower of numbers defined in R5RS
* easy connection to the GTK+ toolkit
* Perl compatible regular expressions thanks to the PCRE package.
* tail recursive calls are properly implemented

Changes in this release:

This is a release with important changes to support
multi-threading. This version provides two kinds of threads:
synchronous LURC threads and asynchronous Posix threads (aka
pthreads). LURC threads are implemented using the LURC library, the
Light ULM/Reactive library for C developed at INRIA. LURC supports the
creation of synchronous cooperative threads, synchronizing and
communicating with each other using signals in a deterministic
scheduler (see http://www-sop.inria.fr/mimosa/Stephane.Epardaud/lurc
for details). Other changes:

* Better error messages
* Added the possibility to compile byte-codes to a C file.
* New optimizations
* More customizable REPL
* New primitives
o read-byte
o write-byte
o printf
o fprintf
o base64-{en|de}code
o current-second
* New implemented SRFI-18 (Multithreading support)
* Bug fixes
