20110404 5.9 release for upload to ftp.gnu.org

20110402
	+ various build-fixes for the rpm/dpkg scripts.
	+ add "--enable-rpath-link" option to Ada95/configure, to allow
	  packages to suppress the rpath feature which is normally used for
	  the in-tree build of sample programs.
	+ corrected definition of libdir variable in Ada95/src/Makefile.in,
	  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.

20110329
	> 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
	  that sample program.
	+ correct typo in check of $PKG_CONFIG variable in Ada95/configure
	+ add ncurses_compat.c, to supply functions used in the Ada95 binding
	  which were added in 5.7 and later.
	+ modify sed expression in CF_NCURSES_ADDON to eliminate a dependency
	  upon GNU sed.

20110326
	+ add special check in Ada95/configure script for ncurses6 reentrant
	  code.
	+ regen Ada html documentation.
	+ build-fix for Ada shared libraries versus the varargs workaround.
	+ add rpm and dpkg scripts for Ada95 and test directories, for test
	  builds.
	+ update test/configure macros CF_CURSES_LIBS, CF_XOPEN_SOURCE and
	  CF_X_ATHENA_LIBS.
	+ add configure check to determine if gnat's project feature supports
	  libraries, i.e., collections of .ali files.
	+ make all dereferences in Ada95 samples explicit.
	+ fix typo in comment in lib_add_wch.c (patch by Petr Pavlu).
	+ add configure check for, ifdef's for math.h which is in a separate
	  package on Solaris and potentially not installed (report by Petr
	  Pavlu).
	> fixes for Ada95 binding (Nicolas Boulenguez):
	+ improve type-checking in Ada95 by eliminating a few warning-suppress
	  pragmas.
	+ suppress unreferenced warnings.
	+ make all dereferences in binding explicit.

20110319
	+ regen Ada html documentation.
	+ change order of -I options from ncurses*-config script when the
	  --disable-overwrite option was used, so that the subdirectory include
	  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
	  distributed separately (report by Nicolas Boulenguez).
	+ modify configure script to add -g and/or -O3 to ADAFLAGS if the
	  CFLAGS for the build has these options.
	+ amend change from 20070324, to not add 1 to the result of getmaxx
	  and getmaxy in the Ada binding (report by Nicolas Boulenguez for
	  thread in comp.lang.ada).
	+ build-fix Ada95/samples for gnat 4.5
	+ spelling fixes for Ada95/samples/explain.txt
	> fixes for Ada95 binding (Nicolas Boulenguez):
	+ add item in Trace_Attribute_Set corresponding to TRACE_ATTRS.
	+ add workaround for binding to set_field_type(), which uses varargs.
	  The original binding from 990220 relied on the prevalent
	  implementation of varargs which did not support or need va_copy().
	+ add dependency on gen/Makefile.in needed for *-panels.ads
	+ add Library_Options to library.gpr
	+ add Languages to library.gpr, for gprbuild

20110307
	+ revert changes to limit-checks from 20110122 (Debian #616711).
	> minor type-cleanup of Ada95 binding (Nicolas Boulenguez):
	+ corrected a minor sign error in a field of Low_Level_Field_Type, to
	  conform to form.h.
	+ replaced C_Int by Curses_Bool as return type for some callbacks, see
	  fieldtype(3FORM).
	+ modify samples/sample-explain.adb to provide explicit message when
	  explain.txt is not found.

20110305
	+ improve makefiles for Ada95 tree (patch by Nicolas Boulenguez).
	+ fix an off-by-one error in _nc_slk_initialize() from 20100605 fixes
	  for compiler warnings (report by Nicolas Boulenguez).
	+ modify Ada95/gen/gen.c to declare unused bits in generated layouts,
	  needed to compile when chtype is 64-bits using gnat 4.4.5

	  a new install of hashed database.
	+ fix typo in Ada95/mk-1st.awk which causes error with original awk.

20110220
	+ configure script rpath fixes from xterm #269.

	+ add U8 feature to denote entries for terminal emulators which do not
	  support VT100 SI/SO when processing UTF-8 encoding -TD
	+ improve the NCURSES_NO_UTF8_ACS feature by adding a check for an
	  extended terminfo capability U8 (prompted by mailing list
	  discussion).

20110122
	+ start documenting interface changes for upcoming 5.8 release.
	+ correct limit-checks in derwin().

	  wide-character configuration.
	+ correct a comparison in wins_nwstr() (Redhat #661506).
	+ correct help-messages in some of the test-programs, which still
	  referred to quitting with 'q'.

20101204
	+ add special case to _nc_infotocap() to recognize the setaf/setab

	  e.g., when using that to configure the test-programs without the
	  rpath feature (request by Sven Joachim).
	+ repurpose "gnome" terminfo entries as "vte", retaining "gnome" items
	  for compatibility, but generally deprecating those since the VTE
	  library is what actually defines the behavior of "gnome", etc.,
	  since 2003 -TD

20101113
	+ compiler warning fixes for test programs.
	+ various build-fixes for test-programs with pdcurses.
	+ updated configure checks for X packages in test/configure from xterm
	  #267 changes.
	+ add configure check to gnatmake, to accommodate cygwin.

20101106
	+ correct list of sub-directories needed in Ada95 tree for building as
	  a separate package.
	+ modify scripts in test-directory to improve builds as a separate
	  package.

20101023
	+ correct parsing of relative tab-stops in tabs program (report by
	  Philip Ganchev).
	+ adjust configure script so that "t" is not added to library suffix
	  when weak-symbols are used, allowing the pthread configuration to
	  more closely match the non-thread naming (report by Werner Fink).
	+ modify configure check for tic program, used for fallbacks, to a
	  warning if not found.  This makes it simpler to use additonal
	  scripts to bootstrap the fallbacks code using tic from the build
	  tree (report by Werner Fink).

	  inconsistent printer-controls.
	+ fill in no-parameter forms of cursor-movement where a parameterized
	  form is available -TD
	+ fill in missing cursor controls where the form of the controls is
	  ANSI -TD

	+ use POSIX locale in mk-dlls.sh.in rather than en_US (report by Sven
	  Joachim).
	+ add a check in mk-dlls.sh.in to obtain the size of a pointer to
	  distinguish between 32-bit and 64-bit hosts.  The result is stored
	  in mingw_arch

20100925
	+ add "XT" capability to entries for terminals that support both
	  xterm-style mouse- and title-controls, for "screen" which
	  special-cases TERM beginning with "xterm" or "rxvt" -TD
	> patch by Juergen Pfeifer:

	+ modify tic's -I/-C dump to reformat acsc strings into canonical form
	  (sorted, unique mapping) (cf: 971004).
	+ add configure check for pthread_kill(), needed for some old
	  platforms.

20100904
	+ add configure option --without-tests, to suppress building test
	  programs (request by Frederic L W Meunier).

20100828
	+ modify nsterm, xnuppc and tek4115 to make sgr/sgr0 consistent -TD
	+ add check in terminfo source-reader to provide more informative
	  message when someone attempts to run tic on a compiled terminal
	  description (prompted by Debian #593920).
	+ note in infotocap and captoinfo manpages that they read terminal
	  descriptions from text-files (Debian #593920).
	+ improve acsc string for vt52, show arrow keys (patch by Benjamin
	  Sittler).

20100814
	+ document in manpages that "mv" functions first use wmove() to check
	  the window pointer and whether the position lies within the window
	  (suggested by Poul-Henning Kamp).
	+ fixes to curs_color.3x, curs_kernel.3x and wresize.3x manpages (patch

	+ improve configure checks for location of tic and infocmp programs
	  used for installing database and for generating fallback data,
	  e.g., for cross-compiling.
	+ add Markus Kuhn's wcwidth function for compiling MinGW
	+ add special case to CF_REGEX for cross-compiling to MinGW target.

20100731
	+ modify initialization check for win32con driver to eliminate need for
	  special case for TERM "unknown", using terminal database if available
	  (prompted by discussion with Roumen Petrov).

20100703
	+ 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.

20100626
	+ continue integrating changes to use gnatmake project files in Ada95
	  + old gnatmake (3.15) does not produce libraries using project-file;
	    work around by adding script to generate alternate makefile.

20100619
	+ continue integrating changes to use gnatmake project files in Ada95
	  + add configure --with-ada-sharedlib option, for the test_make rule.
	  + move Ada95-related logic into aclocal.m4, since additional checks
	    will be needed to distinguish old/new implementations of gnat.

20100612
	+ start integrating changes to use gnatmake project files in Ada95 tree
	  + add test_make / test_clean / test_install rules in Ada95/src

	  assignments to $LIBS, etc.
	+ fix configure script for combining --with-pthread
	  and --enable-weak-symbols options.

20100522
	+ correct cross-compiling configure check for CF_MKSTEMP macro, by
	  adding a check cache variable set by AC_CHECK_FUNC (report by
	  Pierre Labastie).
	+ simplify include-dependencies of make_hash and make_keys, to reduce
	  the need for setting BUILD_CPPFLAGS in cross-compiling when the
	  build- and target-machines differ.
	+ repair broken-linker configuration by restoring a definition of SP
	  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).

20100515
	+ 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.
	+ fixes for configure script from lynx changes:
	  + improve CF_FIND_LINKAGE logic for the case where a function is
	    found in predefined libraries.
	  + revert part of change to CF_HEADER (cf: 20100424)

20100501
	+ correct limit-check in wredrawln, accounting for begy/begx values
	  (patch by David Benjamin).
	+ fix most compiler warnings from clang.
	+ amend build-fix for OpenSolaris, to ensure that a system header is
	  included in curses.h before testing feature symbols, since they
	  may be defined by that route.

20100424
	+ fix some strict compiler warnings in ncurses library.
	+ modify configure macro CF_HEADER_PATH to not look for variations in
	  the predefined include directories.
	+ improve configure macros CF_GCC_VERSION and CF_GCC_WARNINGS to work
	  with gcc 4.x's c89 alias, which gives warning messages for cases
	  where older versions would produce an error.

20100417
	+ modify _nc_capcmp() to work with cancelled strings.
	+ correct translation of "^" in _nc_infotocap(), used to transform
	  terminfo to termcap strings 
	+ add configure --disable-rpath-hack, to allow disabling the feature
	  which adds rpath options for libraries in unusual places.
	+ improve CF_RPATH_HACK_2 by checking if the rpath option for a given
	  directory was already added.
	+ improve CF_RPATH_HACK_2 by using ldd to provide a standard list of
	  directories (which will be ignored).

20100410
	+ improve win_driver.c handling of mouse:
	  + discard motion events
	  + avoid calling _nc_timed_wait when there is a mouse event
	  + handle 4th and "rightmost" buttons.
	+ quote substitutions in CF_RPATH_HACK_2 configure macro, needed for
	  cases where there are embedded blanks in the rpath option.

20100403
	+ add configure check for exctags vs ctags, to work around pkgsrc.
	+ simplify logic in _nc_get_screensize() to make it easier to see how
	  environment variables may override system- and terminfo-values
	  (prompted by discussion with Igor Bujna).
	+ make debug-traces for COLOR_PAIR and PAIR_NUMBER less verbose.
	+ improve handling of color-pairs embedded in attributes for the
	  extended-colors configuration.
	+ modify MKlib_gen.sh to build link_test with sp-funcs.
	+ build-fixes for OpenSolaris aka Solaris 11, for wide-character
	  configuration as well as for rpath feature in *-config scripts.

20100327
	+ refactor CF_SHARED_OPTS configure macro, making CF_RPATH_HACK more
	  reusable.
	+ improve configure CF_REGEX, similar fixes.
	+ improve configure CF_FIND_LINKAGE, adding add check between system
	  (default) and explicit paths, where we can find the entrypoint in the
	  given library.
	+ add check if Gpm_Open() returns a -2, e.g., for "xterm".  This is
	  normally suppressed but can be overridden using $NCURSES_GPM_TERMS.
	  Ensure that Gpm_Close() is called in this case.

20100320
	+ rename atari and st52 terminfo entries to atari-old, st52-old, use
	  newer entries from FreeMiNT by Guido Flohr (from patch/report by Alan
	  Hourihane).

20100313
	+ 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).

20100306
	+ generate manpages for the *-config scripts, adapted from help2man
	  (suggested by Sven Joachim).
	+ use va_copy() in _nc_printf_string() to avoid conflicting use of
	  va_list value in _nc_printf_length() (report by Wim Lewis).

	+ add Ada95/configure script, to use in tar-file created by
	  Ada95/make-tar.sh
	+ fix typo in wresize.3x (patch by Tim van der Molen).
	+ modify screen-bce.XXX entries to exclude ech, since screen's color

20100220
	+ add make-tar.sh scripts to Ada95 and test subdirectories to help with
	  making those separately distributable.
	+ build-fix for static libraries without dlsym (Debian #556378).
	+ fix a syntax error in man/form_field_opts.3x (patch by Ingo
	  Schwarze).

20100206
	+ update mrxvt terminfo entry -TD
	+ modify win_driver.c to support mouse single-clicks.

	  Miroslav Lichvar).

20100130
	+ use vfork in test/ditto.c if available (request by Mike Frysinger).
	+ miscellaneous cleanup of manpages.
	+ fix typo in curs_bkgd.3x (patch by Tim van der Molen).
	+ build-fix for --srcdir (patch by Miroslav Lichvar).

20100123
	+ for term-driver configuration, ensure that the driver pointer is
	  initialized in setupterm so that terminfo/termcap programs work.
	+ amend fix for Debian #542031 to ensure that wattrset() returns only
	  OK or ERR, rather than the attribute value (report by Miroslav
	  Lichvar).
	+ reorder WINDOWLIST to put WINDOW data after SCREEN pointer, making
	  _nc_screen_of() compatible between normal/wide libraries again (patch

	+ update config.guess, config.sub from
		http://savannah.gnu.org/projects/config
	  (caveat - its maintainer put 2010 copyright date on files dated 2009)

20100102
	+ minor improvement to tic's checking of similar SGR's to allow for the
	  most common case of SGR 0.
	+ modify getmouse() to act as its documentation implied, returning on
	  each call the preceding event until none are left.  When no more
	  events remain, it will return ERR.

20091227
	+ change order of lookup in progs/tput.c, looking for terminfo data
	  first.  This fixes a confusion between termcap "sg" and terminfo
	  "sgr" or "sgr0", originally from 990123 changes, but exposed by
	  20091114 fixes for hashing.  With this change, only "dl" and "ed" are

	  filling of unused entries in a cchar_t array with nulls.
	+ updated nsterm* entries (Benjamin Sittler, Emanuele Giaquinta)
	+ modify _nc_viscbuf2() and _tracecchar_t2() to show wide-character
	  nulls.

	  failure.
	+ eliminate clause 3 from the UCB copyrights in read_termcap.c and
	  tset.c per
		ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change
	  (patch by Nicholas Marriott).
	+ replace a malloc in tic.c with strdup, checking for failure (patch by

	  Garrido Fernandez)
	+ improve some limit-checks related to filename length in reading and
	  writing terminfo entries.
	+ ensure that filename is always filled in when attempting to read
	  a terminfo entry, so that infocmp can report the filename (patch
	  by Nicholas Marriott).

20091128
	+ modify mk-1st.awk to allow tinfo library to be built when term-driver
	  is enabled.
	+ add error-check to configure script to ensure that sp-funcs is
	  enabled if term-driver is, since some internal interfaces rely upon
	  this.

20091121
	+ 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.

20091114

	+ updated man/curs_trace.3x
	+ limit hashing for termcap-names to 2-characters (Ubuntu #481740).
	+ change a variable name in lib_newwin.c to make it clearer which
	  value is being freed on error (patch by Nicholas Marriott).

20091107
	+ improve test/ncurses.c color-cycling test by reusing attribute-
	  and color-cycling logic from the video-attributes screen.
	+ add ifdef'd with NCURSES_INTEROP_FUNCS experimental bindings in form
	  library which help make it compatible with interop applications
	  (patch by Juergen Pfeifer).
	+ add configure option --enable-interop, for integrating changes
	  for generic/interop support to form-library by Juergen Pfeifer

20091031
	+ modify use of $CC environment variable which is defined by X/Open
	  as a curses feature, to ignore it if it is not a single character
	  (prompted by discussion with Benjamin C W Sittler).
	+ add START_TRACE in slk_init
	+ fix a regression in _nc_ripoffline which made test/ncurses.c not show
	  soft-keys, broken in 20090927 merging.
	+ change initialization of "hidden" flag for soft-keys from true to
	  false, broken in 20090704 merging (Ubuntu #464274).

	  discussion with Fabian Groffen in GenToo #206201).
	+ add test/xterm-256color.dat

20091024
	+ quiet some pedantic gcc warnings.
	+ modify _nc_wgetch() to check for a -1 in the fifo, e.g., after a

	  (patch by Eygene Ryabinkin, FreeBSD bin/136223).

20091017
	+ modify handling of $PKG_CONFIG_LIBDIR to use only the first item in
	  a possibly colon-separated list (Debian #550716).

	+ similar change for dg+ccc and dgunix+ccc

20090927
	+ move leak-checking for comp_captab.c into _nc_leaks_tinfo() since
	  that module since 20090711 is in libtinfo.
	+ add configure option --enable-term-driver, to allow compiling with
	  terminal-driver.  That is used in MinGW port, and (being somewhat
	  more complicated) is an experimental alternative to the conventional
	  termlib internals.  Currently, it requires the sp-funcs feature to
	  be enabled.
	+ completed integrating "sp-funcs" by Juergen Pfeifer in ncurses
	  library (some work remains for forms library).

20090919
	+ document return code from define_key (report by Mike Gran).
	+ make some symbolic links in the terminfo directory-tree shorter
	  (patch by Daniel Jacobowitz, forwarded by Sven Joachim).).

	+ change ncv and op capabilities in sun-color terminfo entry to match
	  Sun's entry for this (report by Laszlo Peter).
	+ improve interix smso terminfo capability by using reverse rather than
	  bold (report by Kristof Zelechovski).

20090912
	+ add some test programs (and make these use the same special keys
	  by sharing linedata.h functions):
	  test/test_addstr.c
	  test/test_addwstr.c
	  test/test_addchstr.c
	  test/test_add_wchstr.c
	+ correct internal _nc_insert_ch() to use _nc_insert_wch() when
	  inserting wide characters, since the wins_wch() function that it used
	  did not update the cursor position (report by Ciprian Craciun).

20090906
	+ fix typo s/is_timeout/is_notimeout/ which made "man is_notimeout" not
	  work.
	+ add null-pointer checks to other opaque-functions.
	+ add is_pad() and is_subwin() functions for opaque access to WINDOW

	  in non-blocking mode (patch by Clemens Ladisch).
	+ use PATH_SEPARATOR symbol when substituting into run_tic.sh, to
	  help with builds on non-Unix platforms such as OS/2 EMX.
	+ modify scripting for misc/run_tic.sh to test configure script's
	  $cross_compiling variable directly rather than comparing host/build
	  compiler names (prompted by comment in GenToo #249363).
	+ fix configure script option --with-database, which was coded as an
	  enable-type switch.
	+ build-fixes for --srcdir (report by Frederic L W Meunier).

20090808
	+ separate _nc_find_entry() and _nc_find_type_entry() from
	  implementation details of hash function.

20090803
	+ add tabs.1 to man/man_db.renames
	+ modify lib_addch.c to compensate for removal of wide-character test
	  from unctrl() in 20090704 (Debian #539735).

20090801

20090725
	+ continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090718
	+ fix a null-pointer check in _nc_format_slks() in lib_slk.c, from
	  20070704 changes.
	+ modify _nc_find_type_entry() to use hashing.
	+ make CCHARW_MAX value configurable, noting that changing this would
	  change the size of cchar_t, and would be ABI-incompatible.
	+ modify test-programs, e.g,.  test/view.c, to address subtle
	  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).
