Add :decoding-error arg to compile-file to specify how decoding errors
should be handled.

o Add DECODING-ERROR slot to SOURCE-INFO structure.
o MAKE-FILE-SOURCE-INFO requires a decoding error argument so the
  SOURCE-INFO structure can be properly initialized.
o Add :DECODING-ERROR keyword arg to COMPILE-FILE to specify how
  decoding errors are handled.  Default is T, which means to signal an

o Tell compiler about the new parameter.

o Document change.

5 The CMUCL project is pleased to announce the release of CMUCL 20c.
6 This is a major release which contains numerous enhancements and
7 bug fixes from the 20b release.
9 CMUCL is a free, high performance implementation of the Common Lisp
10 programming language which runs on most major Unix platforms. It
11 mainly conforms to the ANSI Common Lisp standard. CMUCL provides a
12 sophisticated native code compiler; a powerful foreign function
13 interface; an implementation of CLOS, the Common Lisp Object System,
14 which includes multi-methods and a meta-object protocol; a source-level
15 debugger and code profiler; and an Emacs-like editor implemented in
16 Common Lisp. CMUCL is maintained by a team of volunteers collaborating
17 over the Internet, and is mostly in the public domain.
19 New in this release:
21 * Known issues:
23 * Feature enhancements
24 - Update to Unicode 5.2.0.
25 - Add support for character name completion. This can be used by
26 Slime to do character name completion.
28 * Changes
29 - COMPILE-FILE now accepts a :DECODING-ERROR argument that
30 indicates how to handle decoding errors when reading the file.
31 It has the same meaning and effect as the :DECODING-ERROR
32 argument to OPEN. This defaults to T here so that decoding
33 errors are signaled on invalid sequences instead of silently
34 replacing the bad sequence with some kind of replacement
35 character.
37 * ANSI compliance fixes:
39 * Bugfixes:
40 - The pairwise composition table is now correctly built.
41 Previously, it skipped over non-BMP codepoints. This also
42 requires a fix in %COMPOSE to handle non-BMP codepoints
43 correctly. The normalization test now passes.
45 * Trac Tickets:
47 * Other changes:
49 * Improvements to the PCL implementation of CLOS:
51 * Changes to building procedure:
53 This release is not binary compatible with code compiled using CMUCL
54 20b; you will need to recompile FASL files.
56 See <URL:http://www.cons.org/cmucl/> for download information,
57 guidelines on reporting bugs, and mailing list details.
60 We hope you enjoy using this release of CMUCL!
