lisp/ChangeLog addition:
2010-02-22 Ben Wing <ben@xemacs.org>
* mule/make-coding-system.el:
* mule/make-coding-system.el (fixed-width-generate-helper):
* mule/make-coding-system.el (fixed-width-private-use-start): Removed.
* mule/make-coding-system.el (fixed-width-create-decode-encode-tables):
* coding.el:
* coding.el (decode-char): New.
* coding.el (featurep):
* coding.el (encode-char): New.
* dumped-lisp.el (preloaded-file-list):
Dump make-coding-system. Aidan's hack to avoid dumping this file
never really worked right -- with some configurations (not clear
exactly which ones) `make-coding-system.el' gets dumped anyway due to
calls to `make-coding-system' in unicode.el, with the result that
the documentation of functions in make-coding-system.el gets lost.
Also needed to remove defvar fixed-width-private-use-start and
incorporate it inline, due to bootstrapping issues -- the call to
decode-char introduced a cross-dependency between unicode.el and
make-coding-system.el.
