[Chicken-users] Chicken 1.33 release

[felix]

The CHICKEN Scheme-to-C compiler, Version 1, Build 33 is now
available at <http://www.call-with-current-continuation.org/chicken.html>.

Things changed since the last release (1.22):
- Countless bugfixes and minor enhancements
- The built-in FFI parser handles more C/C++ and contains many
  improvements (check out the documentation for more information)
- Added runtime-option "-:hm" for setting the maximal heap size
- The file "default-entry-points.scm" provides some boilerplate
  entry-points that make embedding compiled Scheme much easier
- Wrapped C++ classes are handled more transparently
- The doc directory contains some basic TinyCLOS examples
  (file doc/tinyclos-examples.scm)
- New foreign type specifiers:
  instance
  enum
- new syntax:
  foreign-code
  foreign-value
- library:
  print-backtrace
  enable-warnings
- eval:
  repl-prompt
  renamed `read-eval-print-loop' to `repl'
- syntax-case:
  install-highlevel-macro-system
- extras:
  for-each-argv-line
  `pp' is an alias for `pretty-print'
- tinyclos:
  <integer>
- srfi-4:
  subu8vector
  subs8vector
  subu16vector
  subs16vector
  subu32vector
  subs32vector
  subf32vector
  subf64vector
- lolevel:
  renamed `copy', `become!' (among others) to something less generic
   (`object-copy', `object-become!' ...)
- Removed the `-setup' option from csi (the interpreter), all the setup stuff
  is done now by a separate script called (surprise!) `chicken-setup'
- The regex library unit uses PCRE ("Perl Compatible Regular Expressions"), if
  installed on the system where Chicken is built
