Chicken

Two new units, srfi-69 and data-structures, have been factored out from unit extras. Lexicographic version comparison in chicken-setup has been eliminated, so egg version dependencies are handled properly. file-copy and file-remove have been added to unit utils.

The semantics of chicken-setup have been changed
to allow sandbox-type installation of libraries.
MinGW support has been improved. Unit regex has
been updated to use PCRE 7.6. There have been many
additions and fixes to the posix unit and to the
hashtable functions in the extras unit.

chicken-setup now accesses a separate set of eggs, specific to the major CHICKEN version. Support for Mac OS X universal binaries has been added. Additions were made to the units library, POSIX, and the core macros. The build system now supports libpcre already being installed.

Literals are compiled in a platform-independent binary encoding into the executable, which results in faster C compile times and more compact binaries. New procedures in regex and POSIX library units. Bugfixes in file-size, file-stat, and find-files. The "chicken-bug" program can now be used to create bug reports and send them to the CHICKEN maintainers. Many build system improvements. Cygwin is now fully supported, and there is better cross-compilation support. A number of deprecated functions have been removed.
