2010-11-25 Kenichi Handa <handa@m17n.org>
* charset.c (emacs_mule_charset): Make it an array of charset ID;
i.e. integer.
(Fdefine_charset_internal): Adjusted for the above change.
(init_charset_once): Likewise.
* charset.h (emacs_mule_charset): Adjust the prototype. Delete
duplicated extern.
* coding.c (emacs_mule_char): Adjust for the change of
emacs_mule_charset.
* lread.c (read_emacs_mule_char): Adjust for the change of
emacs_mule_charset.
2010-10-18 Ken Brown <kbrown@cornell.edu>
* s/cygwin.h (SIGNALS_VIA_CHARACTERS): New define (bug#7225).
