+ modify make_db_path() to allow creating "terminfo.db" in the same
directory as an existing "terminfo" directory. This fixes a case
where switching between hashed/filesystem databases would cause the
new hashed database to be installed in the next best location -
root's home directory.
+ add variable cf_cv_prog_gnat_correct to those passed to
config.status, fixing a problem with Ada95 builds (cf: 20111022).

accommodate broken implementations for _XPG6.
+ eliminate usage of NULL symbol from etip.h, to reduce header
interdependencies.
+ add configure check to decide when to add _XOPEN_SOURCE define to
compiler options, i.e., for Solaris 10 and later (cf: 20100403).
This is a workaround for gcc 4.6, which fails to build the c++
binding if that symbol is defined by the application, due to
incorrectly combining the corresponding feature test macros
(report by Peter Kruse).
+ correct logic for discarding mouse events, retaining the partial
events used to build up click, double-click, etc, until needed
(cf: 20110917).
+ fix configure script to avoid creating unused Ada95 makefile when
gnat does not work.
+ cleanup width-related gcc 3.4.3 warnings for 64-bit platform, for the
internal functions of libncurses. The external interface of courses
uses bool, which still produces these warnings.
+ modify _nc_read_tic_entry() so that hashed-database is checked before
filesystem.
+ updated CF_CURSES_LIBS check in test/configure script.
+ modify configure script and makefiles to split TIC_ARGS and
TINFO_ARGS into pieces corresponding to LDFLAGS and LIBS variables,
to help separate searches for tic- and tinfo-libraries (patch by Nick
Alcock aka "Nix").
+ build-fix for lib_mouse.c changes (ch: 20110917).
+ modify misc/gen_edit.sh to select a "linux" entry which works with
the current kernel rather than assuming it is always "linux3.0"
(cf: 20110716).
+ revert a change to getmouse() which had the undesirable side-effect
of suppressing button-release events (report by Damien Guibouret,
cf: 20100102).
+ add xterm+kbs fragment from xterm #272 -TD
+ add configure option --with-pkg-config-libdir to provide control over
the actual directory into which pc-files are installed, do not use
the pkg-config environment variables (discussion with Frederic L W
Meunier).
+ add link to mailing-list archive in announce.html.in, as done in
FAQ (prompted by question by Andrius Bentkus).
+ improve manpage install by adjusting the "#include" examples to
show the ncurses-subdirectory used when --disable-overwrite option
is used.
+ install an alias for "curses" to the ncurses manpage, tied to the
--with-curses-h configure option (suggested by Reuben Thomas).

variable is defined in the makefiles which use it.
+ build-fix for DragonFlyBSD's pkgsrc in test/configure script.
+ build-fixes for NetBSD 5.1 with termcap support enabled.
+ corrected k9 in dg460-ansi, add other features based on manuals -TD

field are translated to a non-delimiter, i.e., "=".
+ add "-0" option to tic/infocmp, to make the termcap/terminfo source
use a single line.
+ add a null-pointer check when handling the $CC variable.
+ modify configure script and makefiles in c++ and progs to allow the
directory used for rpath option to be overridden, e.g., to work
around updates to the variables used by tic during an install.
+ add -K option to tic/infocmp, to provide stricter BSD-compatibility
for termcap output.
+ add _nc_strict_bsd variable in tic library which controls the
"strict" BSD termcap compatibility from 20110723, plus these
features:
+ allow escapes such as "\8" and "\9" when reading termcap
+ disallow "\a", "\e", "\l", "\s" and "\:" escapes when reading
termcap files, passing through "a", "e", etc.
+ expand "\:" as "\072" on output.
+ modify _nc_get_token() to reset the token's string value in case
there is a string-typed token lacking the "=" marker.
+ fix a few memory leaks in _nc_tgetent.
+ fix a few places where reading from a termcap file could refer to
freed memory.
+ add an overflow check when converting terminfo/termcap numeric
values, since terminfo stores those in a short, and they must be
positive.
+ correct internal variables used for translating to termcap "%>"
feature, and translating from termcap %B to terminfo, needed by
tctest (cf: 19991211).
+ amend a minor fix to acsc when loading a termcap file to separate it
from warnings needed for tic (cf: 20040710)
+ modify logic in _nc_read_entry() and _nc_read_tic_entry() to allow
a termcap file to be handled via TERMINFO_DIRS.
+ modify _nc_infotocap() to include non-mandatory padding when
translating to termcap.
+ modify _nc_read_termcap_entry(), passing a flag in the case where
getcap is used, to reduce interactive warning messages.

extended colors are not supported (patch by David Benjamin).
+ modify setcchar to omit no-longer-needed OR'ing of color pair in
the SetAttr() macro (patch by David Benjamin).
+ add kich1 to sun terminfo entry (Yuri Pankov)
+ use bold rather than reverse for smso in sun-color terminfo entry
(Yuri Pankov).
+ improve generation of termcap using tic/infocmp -C option, e.g.,
to correspond with 4.2BSD (prompted by discussion with Yuri Pankov
regarding Schilling's test program):
+ translate %02 and %03 to %2 and %3 respectively.
+ suppress string capabilities which use %s, not supported by tgoto
+ use \040 rather than \s
+ expand null characters as \200 rather than \0
+ modify configure script to support shared libraries for DragonFlyBSD.
+ replace an assert() in _nc_Free_Argument() with a regular null
pointer check (report/analysis by Franjo Ivancic).
+ modify configure --enable-pc-files option to take into account the
PKG_CONFIG_PATH variable (report by Frederic L W Meunier).
+ add/use xterm+tmux chunk from xterm #271 -TD
+ resync xterm-new entry from xterm #271 -TD
+ add E3 extended capability to linux-basic (Miroslav Lichvar)

definition with OpenBSD toolset (Nicholas Marriott).
+ add workaround from xterm #271 changes to ensure that compiler flags
are not used in the $CC variable.
+ improve support for shared libraries, tested with AIX 5.3, 6.1 and
7.1 with both gcc 4.2.4 and cc.
+ modify configure checks for AIX to include release 7.x

at gentoo prefix repository (patch by Michael Haubenwallner).
+ fixes for MirBSD port:
+ set default prefix to /usr.
+ add support for shared libraries in configure script.

+ add a few more checks based on ncurses/link_test.
+ modify MKlib_gen.sh to handle sp-funcs renaming of NCURSES_OUTC type.
+ add case to CF_SHARED_OPTS for Interix (patch by Markus Duft).
+ used ncurses/link_test to check for behavior when the terminal has
not been initialized and when an application passes null pointers
to the library. Added checks to cover this (prompted by Redhat
#707344).
+ modify MKlib_gen.sh to make its main() function call each function
with zero parameters, to help find inconsistent checking for null
pointers, etc.
+ add check in test/configure for use_window, use_screen.
+ add configure-checks for getopt's variables, which may be declared
as different types on some Unix systems.
+ add check in test/configure for some legacy curses types of the
function pointer passed to tputs().

and _XOPEN_SOURCE are undefined (report by Valentin Ochs).
+ update config.guess, config.sub

needed for rpm script.
+ add "--with-shared" option to Ada95/configure script, to allow
making the C-language parts of the binding use appropriate compiler
options if building a shared library with gnat.
> portability fixes for Ada95 binding:
+ add configure check to ensure that SIGINT works with gnat. This is
needed for the "rain" sample program. If SIGINT does not work, omit

is listed first.
+ modify the make-tar.sh scripts to add a MANIFEST and NEWS file.
+ modify configure script to provide value for HTML_DIR in
Ada95/gen/Makefile.in, which depends on whether the Ada95 binding is

GCC_NORETURN, GCC_PRINTFLIKE and GCC_SCANFLIKE on a single line.
+ add hard-reset for rs2 to wsvt25 to help ensure that reset ends
+ continue integrating changes to use gnatmake project files in Ada95
+ add/use configure check to turn on project rules for Ada95/src.
+ revert the vfork change from 20100130, since it does not work.

variable to curses.priv.h, and adjusting for cases where sp-funcs
are used.
+ improve configure macro CF_AR_FLAGS, allowing ARFLAGS environment
variable to override (prompted by report by Pablo Cazallas).
+ add configure option --enable-pthreads-eintr to control whether the
new EINTR feature is enabled.
+ modify logic in pthread configuration to allow EINTR to interrupt
a read operation in wgetch() (Novell #540571, patch by Werner Fink).
+ drop mkdirs.sh, use "mkdir -p".
+ add configure option --disable-libtool-version, to use the
"-version-number" feature which was added in libtool 1.5 (report by
Peter Haering). The default value for the option uses the newer
feature, which makes libraries generated using libtool compatible
with the standard builds of ncurses.
+ updated test/configure to match configure script macros.

+ improve configure CF_FIND_LINKAGE, adding add check between system
(default) and explicit paths, where we can find the entrypoint in the
given library.

normally suppressed but can be overridden using $NCURSES_GPM_TERMS.
Ensure that Gpm_Close() is called in this case.
+ modify install-rule for manpages so that *-config manpages will
install when building with --srcdir (report by Sven Joachim).
+ modify CF_DISABLE_LEAKS configure macro so that the --enable-leaks
option is not the same as --disable-leaks (GenToo #305889).
+ modify #define's for build-compiler to suppress cchar_t symbol from
compile of make_hash and make_keys, improving cross-compilation of
ncursesw (report by Bernhard Rosenkraenzer).
+ modify CF_MAN_PAGES configure macro to replace all occurrences of
TPUT in tput.1's manpage (Debian #573597, report/analysis by Anders
Kaseorg).
+ generate manpages for the *-config scripts, adapted from help2man
(suggested by Sven Joachim).

http://savannah.gnu.org/projects/config
(caveat - its maintainer put 2010 copyright date on files dated 2009)
+ fix case where progs/tput is used while sp-funcs is configure; this
requires save/restore of out-character function from _nc_prescreen
rather than the SCREEN structure (report by Charles Wilson).
+ fix typo in man/curs_trace.3x which caused incorrect symbolic links
+ improved configure macros CF_GCC_ATTRIBUTES, CF_PROG_LINT.

differences between Tru64/Solaris and HPUX/AIX getcchar() return
values.
+ modify length returned by getcchar() to count the trailing null
which is documented in X/Open (cf: 20020427).
+ fixes for test programs to build/work on HPUX and AIX, etc.
+ extend ansi.sys pfkey capability from kf1-kf10 to kf1-kf48, moving
function key definitions from emx-base for consistency -TD

by Kalle Olavi Niemitalo).
+ improve test/ncurses.c 'F' test, show combining characters in color.
+ quiet a false report by cppcheck in c++/cursesw.cc by eliminating
a temporary variable.
+ use _nc_doalloc() rather than realloc() in a few places in ncurses
library to avoid leak in out-of-memory condition (reports by William
Egert and Martin Ettl based on cppcheck tool).

with Charles Wilson).
+ use ncurses*-config scripts if available for test/configure.
+ update test/aclocal.m4 and test/configure
> patches by Charles Wilson:
+ modify CF_WITH_LIBTOOL configure check to allow unreleased libtool
version numbers (e.g. which include alphabetic chars, as well as
digits, after the final '.').
+ improve use of -no-undefined option for libtool by setting an
intermediate variable LT_UNDEF in the configure script, and then
using that in the libtool link-commands.
+ fix an missing use of NCURSES_PUBLIC_VAR() in tinfo/MKcodes.awk

build with tic and term libraries (patch by Charles Wilson).
+ add -no-undefined option to libtool for Cygwin, MinGW, U/Win and AIX
(report by Charles Wilson).

"_nc_" (discussion with Charles Wilson).
+ modify scripts to generate ncurses*-config and pc-files to add
dependency for tinfo library (patch by Charles Wilson).
+ improve comparison of program-names when checking for linked flavors
such as "reset" by ignoring the executable suffix (reports by Charles
Wilson, Samuel Thibault and Cedric Bretaudeau on Cygwin mailing
list).
+ suppress configure check for static/dynamic linker flags for gcc on
Solaris 10, since gcc is confused by absence of static libc, and

dependencies (report/analysis by Ken Dickey).
+ modify waddch_literal(), updating line-pointer after a multicolumn
character is found to not fit on the current row, and wrapping is
done. Since the line-pointer was not updated, the wrapped
multicolumn character was written to the beginning of the current row
(cf: 20041023, reported by "Nick" regarding problem with ncmpc
http://musicpd.org/mantis/bug_view_page.php?bug_id=1930).
+ add a configure-time check to pick a suitable value for
CC_SHARED_OPTS for Solaris (report by Dagobert Michelsen).
+ add configure --with-pkg-config and --enable-pc-files options, along
with misc/gen-pkgconfig.in which can be used to generate ".pc" files
for pkg-config (request by Jan Engelhardt).
+ use $includedir symbol in misc/ncurses-config.in, add --includedir
option.
+ change makefiles to use $ARFLAGS rather than $AR_OPTS, provide a
configure check to detect whether a "-" is needed before "ar"
options.
