* updated plink.sh, from xterm, to work around poor performance of
gcc on Fedora.
* updated configure macros for compiler-warning fixes.
* update config.guess, config.sub
2021/02/18 -
* repair/improve the check for X manpage's section, using a fix from
xterm patch #302.
* if a ".enc" file is found, but no built-in character set
description is found, add that to the internal font-encoding table
to allow it to be used, like the built-in character sets.
* modify annotate-enc to handle the external ".enc" which were used
with the older luit.
2021/02/14 -
* add annotate-enc script, use that to annotate the ".enc" files.
* add built-in encoding apl2 (prompted by patch by Jerome Ibanes).
2021/01/14 -
* minor cleanup of file-descriptors, for readability.
* updated configure macros for quoting/escaping fixes.
* update config.guess, config.sub
2020/10/03 -
* updated configure macros:
+ compiler-warning fixes
+ build-fixes for OpenBSD and macOS
* update config.guess, config.sub
2019/12/31 -
* updated configure macros.
* update config.guess, config.sub
2019/01/06 -
* updated configure macros to work around a non-POSIX feature of
BSDs.
* add a dummy "check" rule to makefile for Arch packages.
* add COPYING file for Arch packages.
* use consistent wording for copyright notice in source-files.

2018/12/11 -
* build-fixes/updates for cygwin to accommodate configure-macro
changes.
* updated configure macros:
+ CF_CC_ENV_FLAGS, add check for preprocessor-options in
$CFLAGS.
+ CF_FUNC_GRANTPT, amend the posix_openpt vs grantpt change to
work with BSDs
+ CF_GNU_SOURCE, fixes a regression for Cygwin. The check for
_DEFAULT_SOURCE should apply to "recent" Cygwin (since early
2016), and except for "NEWLIB" vs "GLIBC" in the test, acts
the same if I pretend that "newlib" is the GNU C library.
Without this, the check falls through to the _XOPEN_SOURCE
test, which breaks the pseudoterminal checks for xterm.
+ CF_LD_RPATH_OPT, suppress check if --disable-rpath is given.
+ CF_XOPEN_SOURCE, add midnightbsd to special cases with freebsd
* update config.guess, config.sub
2018/06/28 -
* modify configure script to avoid using OpenBSD's nonfunctional
POSIX pseudoterminal interface.
* add null-pointer checks for all strings printed in trace calls.
* updated configure macros, deprecating use of _GNU_SOURCE symbol for
DEFAULT_SOURCE, and preferring man2html over groff's html
conversion.
* update config.guess, config.sub
2016/05/08 -
* adapt Solaris fix for C11 changes from xterm #325.
* modify parseArgs to check for a special case, e.g., from xterm,
where a shell command that cannot be exec'd is passed as a single
parameter. For that case, run the command via the shell.
* reset IEXTEN when turning off canonical mode, needed to make lnext
control/V work consistently on BSD platforms (report/patch by
Christian Weisgerber).
* updated configure macros:
CF_FUNC_POLL
add a fallback to checking with posix_openpt(), in case
someone's running the configure script in batch mode.
CF_LD_RPATH_OPT
change FreeBSD to use -Wl,-rpath rather than -rpath
option. According to FreeBSD #178732, either works since
FreeBSD 4.x; however scons does not accept anything except
the -Wl,-rpath form.
CF_WITH_MAN2HTML
use configured shell rather than /bin/sh
CF_XOPEN_SOURCE
add a case for OS/2
* update config.guess, config.sub
2015/07/06 -
* add configure option --with-man2html
* updated configure macros, mostly formatting changes from xterm,
etc.
* update config.guess, config.sub
2014/12/04 -
* add table entries for luit to work as expected with CP865 -- MS-DOS
with Nordic letters. This code page was commonly used on BBSes in
Norway, Denmark and Sweden running the MBBS and compatible systems
in the 90s (patch by Hans Petter Jansson).
* add to search-list for encodings.dir file to accommodate Fedora.
* updated configure macros:
+ add /usr/pkg and /opt/local to help configuring with pkgsrc
and macports.
+ fixes for Clang and MinGW, Solaris and Unixware.
+ improve "docs" rule in makefile.
+ CF_RPATH_HACK: use sort and uniq rather than sort -u, to work
with HPUX 11.11, etc.
+ CF_ADD_LIBS: filter duplicate library names
* update config.guess, config.sub
2013/02/17 -
* bump to 2.0, reflecting changes
* add character-set entries for CP1255 and CNS-11643 planes 1-3 to
allow use of some of the remaining ".enc" files.
* modify -list option to show character set sizes.
* add -prefer option to control the lookup order between iconv,
fontenc, builtin and posix character set data.
* add -show-builtin option to show details of a particular built-in
encoding.
* add -list-builtin option to show built-in encodings embedded. This
is available only for the iconv configuration; the fontenc library
has no API for retrieving the information.
* change defaults for configure script options --enable-iconv and
--enable-fontenc to deprecate the fontenc library.
* replaced existing built-in encoding tables with augmented set
generated from iconv to obviate need for fontenc's tables as a
fallback.
* add prefix translations from IBM-CP to CP ), etc., to make
fontenc's encoding name "ibm-cp866" work with luit.
* add koi8-e to locale-charsets table, to make that encoding work.
* add -show-iconv to show a given encoding from iconv using the
".enc" format.
* add -fill-fontenc option to control output format of -show-fontenc.
* add -show-fontenc option to show a given encoding, e.g., from a
".enc" file using the ".enc" format.
* add -list-fontenc option to show available encodings using the
".enc" files which should be distributed with the fontencoding
library.
* add -list-iconv option to show encodings and corresponding locales
supported in the iconv configuration.
* document -kg0, etc., in manpage.
* revise the help option -h, providing a summary of each option
rather than the abbreviated listing. The abbreviated listing is
still provided when an unrecognized option is encountered.
* improve error recovery in the iconv configuration by falling back
to POSIX encoding if no encoding can be found in the system's
tables.
* apply workaround from xterm patch #279 to make window size set for
pty implementation such as Mac OS X which lose this when opening
the other side of the connection.
* fix issues from Coverity scan; all were minor.
* update config.guess, config.sub
2012/10/14 -
* review/improve no-leaks checking with valgrind.
* add null-pointer checks in copyOut in case a non-8bit encoding was
used with the iconv configuration.
* document environment variables used by luit in its manpage.
* amend the check using nl_langinfo(CODESET) in 2011/10/30 changes,
ignoring that section if the -encoding option was given (report by
Alexios Zavras).
* support --datarootdir option in configure script.
* updated configure macros:
CF_FUNC_GRANTPT
add another step to the test-program.
CF_FUNC_POLL
fix the case where stdin is redirected, e.g., in rpm/dpkg
builds (reported in Debian #676461). Also correct
return-check, which could have been confused by typing on
the keyboard while the check was running.
CF_GCC_ATTRIBUTES
use AC_DEFINE_UNQUOTED() rather than appending to
confdefs.h, since long-ago concern about the ability to
pass-through parameterized macros appears to be not a
problem, testing with 2.13 and 2.52
CF_GCC_VERSION
add workaround for Debian's modification of the version
message
CF_GCC_WARNINGS
add check for clang
CF_PATHSEP
add message to show the actual value used.
CF_PATH_SYNTAX
also match (for substitution) variables such as
${includedir}
CF_WITH_PATH
fix after changes in ncurses to use --datarootdir
CF__GRANTPT_BODY
add an ifdef'd chunk #5 for testing the 'tty' (rather than
'pty') and moved the important 'pty' chunk before opening
the slave device as a simple way of making the test
program lose any possible race between parent/child
processes in initializing both sides of the pseudoterminal
(report by Christian Weisgerber).
miscellaneous
cleanup based on byacc 20121003.
* update config.guess, config.sub
2012/1/29 -
* improve portability of the iconv configuration by checking
alternate forms for the encoding name passed to iconv_open.
* add configure check for working posix_openpt, which may be broken
in Mac OS X's current release 10.7 Lion (report by Kirby Zhou).
* add some error checking for the poll and select logic to avoid
looping when a file descriptor is no longer valid.
* improve configure check for working poll function to avoid using
Mac OS X's broken implementation (tested with Darwin 10.8.0).
* updated configure script macros:
CF_FUNC_GRANTPT
modify check to exclude Darwin 9.x and lower from using
posix_openpt. Bug report for xterm by Christian Ebert for
9.8.0 says screensize does not work for the pty.
CF_XOPEN_SOURCE
fixes for redefinition of _XOPEN_SOURCE on a few
platforms: Mac OS X, IRIX64. Also workarounds for header
inconsistencies with OpenBSD and MirBSD.
2011/10/30 -
* modify configure script to add X_LIBS symbol after resolving
fontenc library, to use the associated -L option in subsequent
configure-checks.
* add -t to simplify testing available locales versus luit's tables
and the locale.alias file.
* add "US-ASCII" for C/POSIX to the locale-charset table.
* add entries to the locale-charset table to correspond with the
font-encoding table, making it possible to use locales defined with
each named charset (reported by Andrey Ivanov, also reported in
Freedesktop #41857).
* modify the lookup by locale charset to help match results from
nl_langinfo(CODESET) by mapping commonly used prefixes into the
prefixes used by luit.
* check for, and use nl_langinfo(CODESET) to augment X's
locale.aliases file for determining the encoding to use.
* workaround limitation in copying terminal settings on Solaris from
original tty to pty.
* add /usr/openwin/lib/locale to search-list of locale.alias for
Solaris 10.
* improve configure script so that it does not error-out if fontenc
is unavailable, using iconv instead.
* bump version to 1.2, noting xorg hackers having marked (with only
cosmetic changes) the 2010/6/1 snapshot as "1.1.0".
* add/use configure check for posix_openpt, prompted by FreeBSD
ports/161480.
* updated configure script macros: CF_ANSI_CC_CHECK
CF_DISABLE_RPATH_HACK CF_LD_RPATH_OPT CF_PKG_CONFIG CF_RPATH_HACK
CF_SVR4 CF_WITH_ZLIB CF_XOPEN_SOURCE
* update config.guess, config.sub
2010/11/28 -
* use plink.sh script from xterm to reduce unneeded library
dependencies, e.g., from fontenc's buggy package script.
* eliminate quoted- and duplicate-includes.
* make -g0 and similar options actually work, by adding checks in
initIso2022.
* add messages for the repeated -v option, to show which parts of the
font-encoding configuration fail, for troubleshooting.
* add configure option --disable-leaks, etc.
* add configure option --enable-trace.
* add configure option --enable-iconv, to use GNU iconv, which is far
more portable than fontenc.
+ Initially, this supports single-byte encodings such as
ISO-8859-x.
+ DEC special and technical character sets are supported via
custom tables.
* use static variables and functions consistently, where external
linkage is not required.
* updated configure script macros, e.g., to deprecate shell syntax no
longer supported by bash.
* modify manpage to use "misc" category for the miscellaneous Linux
manpages cited in the "SEE ALSO" section, prompted by xorg change
for 1.1.0 version.
Aside from that (and some cosmetic changes to C source, as well as
providing a different configure script), and omitting this
change-log, the xorg 1.1.0 is the same as the 2010/6/1 version. Its
release notes state:

functions & headers
(adds configure checks for functions and headers used to open
pty's, uses that to replace a derived #define for HAVE_POLL,
#ifdef's the corresponding headers and modifies #ifdef for
I_PUSH ioctl to add __SVR4).
* updated configure script macros: CF_ADD_CFLAGS CF_ADD_INCDIR
CF_ADD_LIBDIR CF_ADD_SEARCHPATH CF_FIND_LINKAGE CF_GCC_ATTRIBUTES

upon locale.
* set ncurses' NCURSES_NO_UTF8_ACS environment variable to simplify
use of line-drawing characters in luit.
