+ build-fix in picsmap.c for stdint.h existence.
+ add --disable-stripping option to configure scripts.
+ modify ncurses-examples to install test-scripts in the data directory.
+ work around tool-breakage in Debian 9 and later by invoking
gprconfig to specify the C compiler to be used by gnatmake,
and conditionally suppressing Library_Options line for static
libraries.
+ bump the compat level for test-packages to 7, i.e., Debian 5.
+ fixes for writing extended color pairs in putwin.
+ modify test/savescreen.c to add test patterns that exercise 88-,
256-, etc., colors.
+ modify configure option --with-build-cc, adding clang, c89 and c99
as possible default values.
+ modify ncurses-examples configure script to use pkg-config for the
extra form/menu/panel libraries, to be more consistent with the
handling of the curses/ncurses library.
+ modify test-packages for mingw to supply "pc" files.
+ modify gen-pkgconfig.in to list -lpthread as a private library when
configured to access it via weak symbols.
+ simplify gen-pkgconfig.in, adding -ltinfo without the special linker
checks because some versions of the linker simply hard-code the
behavior.
+ update URLs for ncurses website to use https.
+ modify CF_CURSES_LIBS to fill in $cf_nculib_root in case the
ncurses-examples are built with a system ncurses that lacks the
standard "curses" symbolic link, as done by SuSE. The symbol is
needed to make a followup check for the pthread library work, and
would be set properly using the options "--with-screen", etc.
+ generate misc/*.pc with "all" rule, as done for "sources" rule
(report by Jeffrey Walton).
+ build-fix for ncurses-examples with Fedora27, adding check for
reset_color_pairs() -- not yet in Fedora's package.
+ consistently add $CFLAGS to $MK_SHARED_LIB symbol in configure
script when the latter happens to use the C compiler rather than
directly using the loader (report by Jeffrey Walton).
+ set ABI for upcoming 6.1 release in "*.map" files. While there are
some remaining internals to apply, no ABI-related changes are
anticipated.
+ add configure --with-config-suffix option to work around filename
conflict with Redhat packages versus test-packages.
+ modify misc/ncurses-config.in to make output with --includedir
consistent with --cflags, i.e., when --disable-overwrite option was
configured the output should show the subdirectory where headers
are.
+ modify MKlib_gen.sh to suppress macros when calling an "implemented"
function in link_test.c
+ updated ftp-url used in test-packages, etc.
+ modify order of -pie/-shared options in configure script in case
LDFLAGS uses "-pie", working around a defect or limitation in the GNU
linker (prompted by patch by Yogesh Prasad, forwarded by Jay Shah).
+ add entry in man_db.renames for user_caps.5
+ modify MKlib_gen.sh to avoid tracing result from getstr/getnstr
before initialized.
+ add "-a" aspect-ratio option to picsmap.
+ add configure check for default path of rgb.txt, used in picsmap.
+ modify _nc_write_entry() to truncate too-long filename (report by
Hosein Askari, Debian #882620).
+ build-fix for ncurses-examples with NetBSD curses:
+ it lacks the use_env() function.
+ it lacks libpanel; a recent change used the wrong ifdef symbol.
+ add a macro for is_linetouched() and adjust the function's return
value to make it possible for most applications to check for an
error-return (report by Midolikawa H).
+ additional manpage cleanup.
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ fix a symbol conflict that made ncurses.c C/c menu not work with
Solaris xpg4 curses.
+ add refresh() call to dots_mvcur.c, needed to use mvcur() with
Solaris xpg4 curses after calling newterm().
+ minor fixes for configure script from work on ncurses-examples and
tin.
+ improve animation in test/xmas.c by adding a time-delay in blinkit().
+ modify several test programs to reflect that ncurses honors existing
signal handlers in initscr(), while other implementations do not.
+ modify bs.c to make it easier to quit.
+ change ncurses-examples to use attr_t vs chtype to follow X/Open
documentation more closely since Solaris xpg4-curses uses different
values for WA_xxx vs A_xxx that rely on attr_t being an unsigned
short. Tru64 aka OSF1, HPUX, AIX did as ncurses does, equating the
two sets.
+ improve description of -R option in infocmp manual page (report by
Stephane Chazelas).
+ add reset_color_pairs() function.
+ add user_caps.5 manual page to document the terminfo extensions used
by ncurses.
+ improve build scripts, using SIGQUIT vs SIGTRAP; add other configure
script fixes from work on xterm, lynx and tack.
+ modify install-rule for ncurses-examples to put the data files in
/usr/share/ncurses-examples
+ improve tracemunch, by changing address-parameters of add_wch(),
color_content() and pair_content() to dummy parameters.
+ minor optimization to _nc_change_pair, to return quickly when the
current screen is marked for clearing.
+ in-progress changes to improve performance of test/picsmap.c for
loading image files.
+ modify allocation for SCREEN's color-pair table to start small, grow
on demand up to the existing limit.
+ add "RGB" extension capability for direct-color support, use this to
improve color_content().
+ improve picsmap test-program:
+ if no palette file is needed, attempt to load one based on $TERM,
checking first in the current directory, then by adding ".dat"
suffix, and finally in the data-directory, e.g.,
/usr/share/ncurses-examples
+ add "-l" option for logging
+ add "-d" option for debugging
+ add "-s" option for stepping automatically through list of images,
with time delay.
+ use tsearch to improve time for loading color table for images.
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ update interix entry using tack and SFU on Windows 7 Ultimate -TD
+ use ^? for kdch1 in interix (reported by Jonathan de Boyne Pollard)
+ add "rep" to xterm-new, available since 1997/01/26 -TD
+ move SGR 24 and 27 from vte-2014 to vte-2012 (request by Alain
Williams) -TD
+ add a check in newline_forces_scroll() in case a program moves the
cursor outside scrolling margins (report by Robert King).
+ improve _nc_tparm_analyze, using that to extend the checks made by
tic for reporting inconsistencies between the expected number of
parameters for a capability and the actual.
+ amend handling of repeat_char capability in EmitRange (adapted from
report/patch by Dick Wesseling):
+ translate the character to the alternate character set when the
alternate character set is enabled.
+ do not use repeat_char for characters past 255.
+ document "_nc_free_tinfo" in manual page, because it could be used in
tack for memory-leak checking.
+ add "--without-tack" configure option to refine "--with-progs"
configure option. Normally tack is no longer built in-tree, but
a few packagers combine it during the build. If term_entry.h is
installed, there is no advantage to in-tree builds.
+ adjust configure-script to define HAVE_CURSES_DATA_BOOLNAMES symbol
needed for tack 1.08 when built in-tree. Rather than relying upon
internal "_nc_" functions, tack now uses the boolean, number and
string capability name-arrays provided by ncurses and SVr4 Unix
curses. It still uses term_entry.h for the definitions of the
extended capability arrays.
+ add an overlooked null-pointer check in mvcur changes from 20170722
+ corrected a case where $with_gpm was set to "maybe" after CF_WITH_GPM,
overlooked in 20160528 fixes (report by Alexandre Bury).
+ improve a couple of test-program's help-messages.
+ corrected loop in rain.c from 20170415 changes.
+ modify winnstr and winchnstr to return error if the output pointer is
null, as well as adding a null pointer check of the window pointer
for better compatibility with other implementations.
+ improve discussion of NetBSD curses in scr_dump.5
+ modify LIMIT_TYPED macro in new_pair.h to avoid changing sign of the
value to be limited (reports by Darby Payne, Rob Boudreau).
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ build-fixes for PGI compilers (report by Adam J. Stewart)
+ accept whitespace in sed expression for generating expanded.c
+ modify configure check that g++ compiler warnings are not used.
+ add configure check for -fPIC option needed for shared libraries.
+ let configure --disable-ext-funcs override the default for the
--enable-sp-funcs option.
+ mark some structs in form/menu/panel libraries as potentially opaque
without modifying API/ABI.
+ add configure option --enable-opaque-curses for ncurses library and
similar options for the other libraries.
+ incorporate A_COLOR mask into COLOR_PAIR(), in case user application
provides an out-of-range pair number (report by Elijah Stone).
+ clarify description in tput manual page regarding support for
termcap names (prompted by FreeBSD #214709).
+ remove a restriction in tput's support for termcap names which
omitted capabilities normally not shown in termcap translations
(cf: 990123).
+ modify configure script for clang as used on FreeBSD, to work around
clang's differences in exit codes vs gcc.
+ fix errata for ncurses-howto (report by Damien Ruscoe).
+ fix a few places in configure/build scripts where DESTDIR and rpath
were combined (report by Thomas Klausner).
+ merge current st description (report by Harry Gindi) -TD
+ modify flash capability for linux and wyse entries to put the delay
between the reverse/normal escapes rather than after -TD
+ modify program tabs to pass the actual tty file descriptor to
setupterm rather than the standard output, making padding work
consistently.
+ explain in clear's manual page that it writes to stdout.
+ add special case for verbose debugging traces of command-line
utilities which write to stderr (cf: 20161126).
+ remove a trace with literal escapes from skip_DECSCNM(), added in
20161203.
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ adjust size in infocmp/tic to work with strlcpy.
+ fix configure script to record when strlcat is found on OpenBSD.
+ build-fix for "recent" OpenBSD vs baudrate.
+ trim dead code ifdef'd with HIDE_EINTR since 970830 (discussion with
Leon Winter).
+ trim some obsolete/incorrect wording about EINTR from wgetch manual
page (patch by Leon Winter).
+ really correct 20100515 change (patch by Rich Coe).
+ add "--enable-string-hacks" option to test/configure
+ completed string-hacks for "sprintf", etc., including test-programs.
+ make "--enable-string-hacks" work with Debian by checking for the
"bsd" library and its associated "<bsd/string.h>" header.
+ correct 20100515 change for weak signals versus sigprocmask (report
by Rich Coe).
+ modify misc/Makefile.in to work around OpenBSD "make" which unlike
all other versions of "make" does not recognize continuation lines
of comments.
+ amend the last change to CF_C_ENV_FLAGS to move only the
preprocessor, optimization and warning flags to CPPFLAGS and CFLAGS,
leaving the residue in CC. That happens to work for gcc's various
"model" options, but may require tuning for other compilers (report
by Sven Joachim).
+ add "v" menu entry to test/ncurses.c to show baudrate and other
values.
+ add "newer" baudrate symbols from Linux and FreeBSD to progs/tset.c,
lib_baudrate.c
+ modify CF_XOPEN_SOURCE macro:
+ add "uclinux" to case for "linux" (patch by Yann E. Morin)
+ modify _GNU_SOURCE for cygwin headers, tested with cygwin 2.3, 2.5
(patch by Corinna Vinschen, from changes to tin).
+ improve CF_CC_ENV_FLAGS macro to allow for compiler wrappers such
as "ccache" (report by Enrico Scholz).
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ improve CF_GNU_SOURCE configure macro to optionally define
_DEFAULT_SOURCE work around a nuisance in recent glibc releases.
+ move the terminfo-specific parts of tput's "reset" function into
the shared reset_cmd.c, making the two forms of reset use the same
strings.
+ split-out the terminal initialization functions from tset as
progs/reset_cmd.c, as part of changes to merge the reset-feature
with tput.
+ improved manual page description of tset/reset versus window-size.
+ fixes to work with a slightly broken compiler configuration which
cannot compile "Hello World!" without adding compiler options
(report by Ola x Nilsson):
+ pass appropriate compiler options to the CF_PROG_CC_C_O macro.
+ when separating compiler and options in CF_CC_ENV_FLAGS, ensure
that all options are split-off into CFLAGS or CPPFLAGS
+ restore some -I options removed in 20140726 because they appeared
to be redundant. In fact, they are needed for a compiler that
cannot combine -c and -o options.
+ modify test/configure script to check for pthread dependency of
ncursest or ncursestw library when building ncurses examples, e.g.,
in case weak symbols are used.
+ modify configure macro for shared-library rules to use -Wl,-rpath
rather than -rpath to work around a bug in scons (FreeBSD #178732,
cf: 20061021).
+ double-width multibyte characters were not counted properly in
winsnstr and wins_nwstr (report/example by Eric Pruitt).
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ add a paragraph to curs_getch.3x discussing key naming (discussion
with James Crippen).
+ amend workaround for Solaris vs line-drawing to take the configure
check into account.
+ add a configure check for wcwidth() versus the ncurses line-drawing
characters, to use in special-casing systems such as Solaris.
+ modify tset's assignment to TERM in its output to reflect the name by
which the terminal description is found, rather than the primary
name. That was an unnecessary part from the initial conversion of
tset from termcap to terminfo. The termcap program in 4.3BSD did
this to avoid using the short 2-character name (report by Rich
Burridge).
+ minor fix to configure script to ensure that rules for resulting.map
are only generated when needed (cf: 20151101).
+ modify configure script to handle the case where tic-library is
renamed, but the --with-debug option is used by itself without
normal or shared libraries (prompted by comment in Debian #803482).
+ amend change for pkg-config which allows build of pc-files when no
valid pkg-config library directory was configured to suppress the
actual install if it is not overridden to a valid directory at
install time (cf: 20150822).
+ modify editing script which generates resulting.map to work with the
clang configuration on recent FreeBSD, which gives an error on an
empty "local" section.
+ fix a spurious "(Part)" message in test/ncurses.c b/B tests due
to incorrect attribute-masking.
+ modify MKexpanded.c to update the expansion of a temporary filename
to "expanded.c", for use in trace statements.
+ modify layout of b/B tests in test/ncurses.c to allow for additional
annotation on the right margin; some terminals with partial support
did not display well.
+ fix typo in curs_attr.3x (patch by Sven Joachim).
+ fix typo in INSTALL (patch by Tomas Cech).
+ improve configure check for setting WILDCARD_SYMS variable; on ppc64
the variable is in the Data section rather than Text (patch by Michel
Normand).
+ using configure option "--without-fallbacks" incorrectly caused
FALLBACK_LIST to be set to "no" (patch by Tomas Cech).
+ updated minitel entries to fix kel problem with emacs, and add
minitel1b-nb (Alexandre Montaron).
+ reviewed/updated nsterm entry Terminal.app in OSX -TD
+ replace some dead URLs in comments with equivalents from the
Internet Archive -TD
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ modify ncurses/Makefile.in to sort keys.list in POSIX locale
(Debian #801864, patch by Esa Peuha).
+ remove an early-return from _nc_do_color, which can interfere with
data needed by bkgd when ncurses is configured with extended colors
(patch by Denis Tikhomirov).
> fixes for OS/2 (patches by KO Myung-Hun)
+ use button instead of kbuf[0] in EMX-specific part of lib_mouse.c
+ support building with libtool on OS/2
+ use stdc++ on OS/2 kLIBC
+ clear cf_XOPEN_SOURCE on OS/2
+ add configure check for openpty to test/configure script, for ditto.
+ minor fixes to test/view.c in investigating Debian #790847.
+ update autoconf patch to 2.52.20150926, incorporates a fix for Cdk.
+ add workaround for breakage of POSIX makefiles by recent binutils
change.
+ improve check for working poll() by using posix_openpt() as a
fallback in case there is no valid terminal on the standard input
(prompted by discussion on bug-ncurses mailing list, Debian #676461).
+ change makefile rule for removing resulting.map to distclean rather
than clean.
+ add /lib/terminfo to terminfo-dirs in ".deb" test-package.
+ add note on portability of resizeterm and wresize to manual pages.
+ fixes for configure/build using clang on OSX (prompted by report by
William Gallafent).
+ do not redefine "inline" in ncurses_cfg.h; this was originally to
solve a problem with gcc/g++, but is aggravated by clang's misuse
of symbols to pretend it is gcc.
+ add braces to configure script to prevent unwanted add of
"-lstdc++" to the CXXLIBS symbol.
+ improve/update test-program used for checking existence of stdc++
library.
+ if $CXXLIBS is set, the linkage test uses that in addition to $LIBS
+ sort options in usage message for infocmp, to make it simpler to
see unused letters.
+ update usage message for tic, adding "-0" option.
+ documented differences in ESCDELAY versus AIX's implementation.
+ fix some compiler warnings from ports.
+ modify --with-pkg-config-libdir option to make it possible to install
".pc" files even if pkg-config is not found (adapted by patch by
Joshua Root).
+ disallow "no" as a possible value for "--with-shlib-version" option,
overlooked in cleanup-changes for 20000708 (report by Tommy Alex).
+ update release notes in INSTALL.
+ regenerate llib-* files to help with review for release notes.
+ build-fix for Ada95 on older platforms without stdint.h
+ build-fix for Solaris, whose /bin/sh and /usr/bin/sed are non-POSIX.
+ update release announcement, summarizing more than 800 changes across
more than 200 snapshots.
+ minor fixes to manpages, etc., to simplify linking from announcement
page.
+ modify configure script to remove deprecated ABI 5 symbols when
building ABI 6.
+ add symbols _nc_Default_Field, _nc_Default_Form, _nc_has_mouse to
map-files, but marked as deprecated so that they can easily be
suppressed from ABI 6 builds (Debian #788610).
+ comment-out "screen.xterm" entry, and inherit screen.xterm-256color
from xterm-new (report by Richard Birkett) -TD
+ modify read_entry.c to set the error-return to -1 if no terminal
databases were found, as documented for setupterm.
+ add test_setupterm.c to demonstrate normal/error returns from the
setupterm and restartterm functions.
+ amend cleanup change from 20110813 which removed redundant definition
of ret_error, etc., from tinfo_driver.c, to account for the fact that
it should return a bool rather than int (report/analysis by Johannes
Schindelin).
+ make ABI 6 the default by updates to dist.mk and VERSION, with the
intention that the existing ABI 5 should build as before using the
"--with-abi=5" option.
+ regenerate ada- and man-html documentation.
+ minor fixes to color- and util-manpages.
+ fix a regression in Ada95/gen/Makefile.in, to handle special case of
Cygwin, which uses the broken-linker feature.
+ amend fix for CF_NCURSES_CONFIG used in test/configure to assume that
ncurses package scripts work when present for cross-compiling, as the
lessor of two evils (cf: 20150530).
+ add check in configure script to disallow conflicting options
"--with-termlib" and "--enable-term-driver".
+ move defaults for "--disable-lp64" and "--with-versioned-syms" into
CF_ABI_DEFAULTS macro.
+ change private type for Event_Mask in Ada95 binding to work when
mmask_t is set to 32-bits.
+ remove spurious "%;" from st entry (report by Daniel Pitts) -TD
+ add vte-2014, update vte to use that -TD
+ modify tic and infocmp to "move" a diagnostic for tparm strings that
have a syntax error to tic's "-c" option (report by Daniel Pitts).
+ fix two problems with configure script macros (Debian #786436,
cf: 20150425, cf: 20100529).
+ modify the configure script to allow different default values
for ABI 5 versus ABI 6.
+ add wgetch-events to test-packages.
+ add a note on how to build ncurses-examples to test/README.
+ fix a memory leak in delscreen (report by Daniel Kahn Gillmor,
Debian #783486) -TD
+ remove unnecessary ';' from E3 capabilities -TD
+ add tmux entry, derived from screen (patch by Nicholas Marriott).
+ split-out recent change to nsterm-bce as nsterm-build326, and add
nsterm-build342 to reflect changes with successive releases of OSX
(discussion with Leonardo B Schenkel)
+ add xon, ich1, il1 to ibm3161 (patch by Stephen Powell, Debian
#783806)
+ add sample "magic" file, to document ext-putwin.
+ modify gen-pkgconfig.in to add explicit -ltinfo, etc., to the
generated ".pc" file when ld option "--as-needed" is used, or when
ncurses and tinfo are installed without using rpath (prompted by
discussion with Sylvain Bertrand).
+ modify test-package for ncurses6 to omit rpath feature when installed
in /usr.
+ add OSX's "*.dSYM" to clean-rules in makefiles.
+ make extra-suffix work for OSX configuration, e.g., for shared
libraries.
+ modify Ada95/configure script to work with pkg-config
+ move test-package for ncurses6 to /usr, since filename-conflicts have
been eliminated.
+ corrected build rules for Ada95/gen/generate; it does not depend on
the ncurses library aside from headers.
+ reviewed man pages, fixed a few other spelling errors.
+ fix a typo in curs_util.3x (Sven Joachim).
+ use extra-suffix in some overlooked shared library dependencies
found by 20150425 changes for test-packages.
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ avoid a blank line in output from tabs program by ending it with
a carriage return as done in FreeBSD (patch by James Clarke).
+ build-fix for the "--enable-ext-putwin" feature when not using
wide characters (report by Werner Fink).
+ modify autoconf macros to use scripting improvement from xterm.
+ add -brtl option to compiler options on AIX 5-7, needed to link
with the shared libraries.
+ add --with-extra-suffix option to help with installing nonconflicting
ncurses6 packages, e.g., avoiding header- and library-conflicts.
NOTE: as a side-effect, this renames
adacurses-config to adacurses5-config and
adacursesw-config to adacursesw5-config
+ modify debian/rules test package to suffix programs with "6".
+ clarify in curs_inopts.3x that window-specific settings do not
inherit into new windows.
+ add configure check to determine if "local: _*;" can be used in the
".map" files to selectively omit symbols beginning with "_". On at
least recent FreeBSD, the wildcard applies to all "_" symbols.
+ remove obsolete/conflicting rule for ncurses.map from
ncurses/Makefile.in (cf: 20130706).
+ add a step to generating ".map" files, to declare any remaining
symbols beginning with "_" as local, at the last version node.
+ improve configure checks for pkg-config, addressing a variant found
with FreeBSD ports.
+ modify win_driver.c to provide characters for special keys, like
ansi.sys, when keypad mode is off, rather than returning nothing at
all (discussion with Eli Zaretskii).
+ add "broken_linker" and "hashed-db" configure options to combinations
use for generating the ".map" and ".sym" files.
+ avoid using "ld" directly when creating shared library, to simplify
cross-compiles. Also drop "-Bsharable" option from shared-library
rules for FreeBSD and DragonFly (FreeBSD #196592).
+ fix a memory leak in form library Free_RegularExpression_Type()
(report by Pavel Balaev).
+ modify_nc_flush() to retry if interrupted (patch by Stian Skjelstad).
+ change map files to make _nc_freeall a global, since it may be used
via the Ada95 binding when checking for memory leaks.
+ improve sed script used in 20141220 to account for wide-, threaded-
variations in ABI 6.
+ updated Ada95/configure with macro changes from 20141213
+ tie configure options --with-abi-version and --with-versioned-syms
together, so that ABI 6 libraries have distinct symbol versions from
the ABI 5 libraries.
+ replace obsolete/nonworking link to man2html with current one,
regenerate html-manpages.
+ modify misc/gen-pkgconfig.in to add -I option for include-directory
when using both --prefix and --disable-overwrite (report by Misty
De Meo).
+ add configure option --with-pc-suffix to allow minor renaming of
".pc" files and the corresponding library. Use this in the test
package for ncurses6.
+ modify configure script so that if pkg-config is not installed, it
is still possible to install ".pc" files (report by Misty De Meo).
+ updated ".sym" files, removing symbols which are marked as "local"
in the corresponding ".map" files.
+ updated ".map" files to reflect move of comp_captab and comp_hash
from tic-library to tinfo-library in 20090711 (report by Sven
Joachim).
+ updated ".map" files so that each symbol that may be shared across
the different library configurations has the same label. Some
review is needed to ensure these are really compatible.
+ modify MKlib_gen.sh to work around change in development version of
gcc introduced here:
https://gcc.gnu.org/ml/gcc-patches/2014-06/msg02185.htmlhttps://gcc.gnu.org/ml/gcc-patches/2014-07/msg00236.html
(reports by Marcus Shawcroft, Maohui Lei).
+ improved configure macro CF_SUBDIR_PATH, from lynx changes.
+ improve description of limits for color values and color pairs in
curs_color.3x (prompted by patch by Tim van der Molen).
+ add VERSION file, using first field in that to record the ABI version
used for configure --with-libtool --disable-libtool-version
+ add configure options for applying the ".map" and ".sym" files to
the ncurses, form, menu and panel libraries.
+ add ".map" and ".sym" files to show exported symbols, e.g., for
symbol-versioning.
+ add ncurses*-config to bin-directory of sample package-scripts.
+ add check to ensure that getopt is available; this is a problem in
some older cross-compiler environments.
+ expanded on the description of --disable-overwrite in INSTALL
(prompted by reports by Joakim Tjernlund, Thomas Klausner).
See Gentoo #522586 and NetBSD #49200 for examples.
which relates to the clarified guidelines.
+ remove special logic from CF_INCLUDE_DIRS which adds the directory
for the --includedir from the build (report by Joakim Tjernlund).
+ add case for Unixware to CF_XOPEN_SOURCE, from lynx changes.
+ update config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ minor portability fixes for MinGW:
+ ensure WINVER is defined in makefiles rather than using headers
+ add check for gnatprep "-T" option
+ work around bug introduced by gcc 4.8.1 in MinGW which breaks
"trace" feature:
http://stackoverflow.com/questions/20877689/gcc-4-8-1-minggw-d-option-does-not-work-as-usual
+ fix most compiler warnings for Cygwin ncurses-examples.
+ restore "redundant" -I options in test/Makefile.in, since they are
typically needed when building the derived ncurses-examples package
(cf: 20140726).
+ eliminate some redundant -I options used for building libraries, and
ensure that ${srcdir} is added to the include-options (prompted by
discussion with Paul Gilmartin).
+ modify configure script to work with Minix3.2
+ add form library extension O_DYNAMIC_JUSTIFY option which can be
used to override the different treatment of justification for static
versus dynamic fields (adapted from patch by Leon Winter).
+ add a null pointer check in test/edit_field.c (report/analysis by
Leon Winter, cf: 20130608).
+ make workarounds for compiling test-programs with NetBSD curses.
+ improve configure macro CF_ADD_LIBS, to eliminate repeated -l/-L
options, from xterm changes.
