From hiramatu /at/ boreas _dot_ dti _dot_ ne _dot_ jp in PR#29890,
with a few modifications by me.
* ver 4.51 (Jan.16th,2004)
+ fixed keyboard-interrupt handling while reloading a file to
avoid segmentation fault. (pointed out by Masanori GOTO
<gotom@debian.or.jp>)
+ modified definitions of boolean_t, PAGE_SIZE, VDISCARD, and
autoconf for libcurses for AIX. (pointed out by SHIOTA
Shoichi <Shoichi.Shiota@lightwell.co.jp>)
+ omitted to specify owner and group to install command, and
omitted include langinfo.h when HAVE_LANGINFO_CODESET is not
defined, for Max OS X. (pointed out by Koki NAKASHIRO
<nakasiro@sdl.hitachi.co.jp>)
Change summary from the release note:
o Big5 to Unicode mapping didn't work at all (fixed offset of coding
system table)
(See http://lists.debian.or.jp/debian-devel/200311/msg00006.html)
o -D option now specifies default (fall-back) coding system, not default
EUC coding system. This means that -D coding system is used not only
for determination of EUC coding systems but also determination of other
coding systems.
o Added ISO-8859-10,11,13,14,15,16.
o Many bug fixes.
