Import a stock copy of ncurses 5.8 into the vendor space.vendor/ncurses/5.8-20110226

It seems both local changes we made to 5.7 have already been fixed
upstream properly, so there is no need to preserve the changes. Also,
with SVN we import full source trees. Unlike CVS, where we removed
unneeded cruft.

                                  Release Notes
 
    This  release  is  designed  to  be upward compatible from ncurses 5.0
-   through   5.6;  very  few  applications  will  require  recompilation,
+   through   5.7;  very  few  applications  will  require  recompilation,
    depending   on  the  platform.  These  are  the  highlights  from  the
-   change-log since ncurses 5.6 release.
-
-   Interface changes:
-     * generate linkable stubs for some macros:
-       getattrs
-
-   New features and improvements:
-     * library
-          + new  flavor  of  the  ncurses  library  provides  rudimentary
-            support  for  POSIX threads. Several functions are reentrant,
-            but most require either a window-level or screen-level mutex.
-            (This  is  API-compatible,  but  not  ABI-compatible with the
-            normal library).
-          + add  NCURSES_OPAQUE  symbol  to  curses.h,  will  use to make
-            structs opaque in selected configurations.
-          + add   NCURSES_EXT_FUNCS  and  NCURSES_EXT_COLORS  symbols  to
-            curses.h to make it simpler to tell if the extended functions
-            and/or colors are declared.
-          + add wresize() to C++ binding
-          + eliminate fixed-buffer vsprintf() calls in C++ binding.
-          + add  several  functions to C++ binding which wrap C functions
-            that pass a WINDOW* parameter.
-          + adapt mouse-handling code from menu library in form-library
-          + improve  tracing  for  form  library,  showing created forms,
-            fields, etc.
-          + make $NCURSES_NO_PADDING feature work for termcap interface .
-          + add  check  to  trace-file  open,  if  the  given  name  is a
-            directory, add ".log" to the name and try again.
-          + several   new   manpages:  curs_legacy.3x,  curs_memleaks.3x,
-            curs_opaque.3x and curs_threads.3x
-     * programs:
-          + modified  three  test-programs  to  demonstrate the threading
-            support in this version: ditto, rain, worm.
-          + several    new    test-programs:   demo_panels,   dots_mvcur,
-            inch_wide,    inchs,    key_name,    key_names,   savescreen,
-            savescreen.sh    test_arrays,   test_get_wstr,   test_getstr,
-            test_instr, test_inwstr and test_opaque.
-          + add adacurses-config to the Ada95 install.
-          + modify  tic  -f option to format spaces as \s to prevent them
-            from  being  lost  when  that  is  read  back  in unformatted
-            strings.
-          + The tack program is now distributed separately from ncurses.
-     * terminal database
-          + added entries:
-               o Eterm-256color, Eterm-88color and rxvt-88color
-               o aterm
-               o konsole-256color
-               o mrxvt
-               o screen.mlterm
-               o screen.rxvt
-               o teraterm4.59  is now the primary primary teraterm entry,
-                 renamed original to teraterm2.3
-               o 9term terminal
-               o Newbury Data entries
-          + updated/improved entries:
-               o gnome to version 2.22.3
-               o h19, z100
-               o konsole to version 1.6.6
-               o mlterm, mlterm+pcfkeys
-               o xterm, and building-blocks for function-keys to [3]xterm
-                 patch #230.
-
-   Major bug fixes:
-     * add   logic   to   tic  for  cancelling  strings  in  user-defined
-       capabilities (this is needed for current konsole terminfo entry).
-     * modify  mk-1st.awk  so the generated makefile rules for linking or
-       installing  shared  libraries  do not first remove the library, in
-       case it is in use, e.g., libncurses.so by /bin/sh.
-     * correct check for notimeout() in wgetch().
-     * fix a sign-extension bug in infocmp's repair_acsc() function.
-     * change winnstr() to stop at the end of the line.
-     * make Ada95 demo_panels() example work.
-     * fix for adding a non-spacing character at the beginning of a line.
-     * fill   in   extended-color   pair   to   make   colors   work  for
-       wide-characters using extended-colors.
-     * improve  refresh  of  window  on  top  of multi-column characters,
-       taking   into   account  split  characters  on  left/right  window
-       boundaries.
-     * modify  win_wchnstr()  to ensure that only a base cell is returned
-       for each multi-column character.
-     * improve waddch() and winsch() handling of EILSEQ from mbrtowc() by
-       using  unctrl()  to  display  illegal  bytes rather than trying to
-       append further bytes to make up a valid sequence.
-     * restore curs_set() state after endwin()/refresh()
-     * modify  keyname() to use "^X" form only if meta() has been called,
-       or  if  keyname() is called without initializing curses, e.g., via
-       initscr() or newterm().
-     * modify  unctrl() to check codes in 128-255 range versus isprint().
-       If  they  are not printable, and locale was set, use a "M-" or "~"
-       sequence.
-     * improve  resizeterm()  by  moving ripped-off lines, and repainting
-       the soft-keys.
-     * modify  form  library to accept control characters such as newline
-       in set_field_buffer(), which is compatible with Solaris.
-     * use  NCURSES_MOUSE_MASK() in definition of BUTTON_RELEASE(), etc.,
-       to   make   those   work   properly  with  the  --enable-ext-mouse
-       configuration
-     * correct  some  functions  in Ada95 binding which were using return
-       value from C where none was returned.
-     * reviewed/fixed issues reported by Coverity and Klocwork tools.
-
-   Portability:
+   change-log since ncurses 5.7 release.
+
+Interface changes
+
+     * turn on _XOPEN_CURSES definition in curses.h.
+     * change  _nc_has_mouse  to  has_mouse,  reflect  its use in C++ and
+       Ada95.
+     * add is_pad and is_subwin functions for opaque access to the WINDOW
+       structure.
+     * add tiparm, based on review of X/Open Curses Issue 7.
+
+New features and improvements
+
+  Library Improvements
+
+     * add  a terminal driver for Windows console, which supports a MinGW
+       port to Windows.
+     * add  extended  functions  which  specify  the  SCREEN  pointer for
+       several curses functions which use the global SP.
+     * improve  the  NCURSES_NO_UTF8_ACS feature by adding a check for an
+       extended terminfo capability U8.
+     * improve  performance of tigetstr, etc., by using hashing code from
+       tic.
+     * add  WACS_xxx  definitions  to  wide-character  configuration  for
+       thick- and double-lines.
+     * modify  init_pair  to  allow  caller  to  create extra color pairs
+       beyond the color_pairs limit, which use default colors.
+
+  Improvements to Programs
+
+     * add tabs program.
+     * modify  tic's  -I/-C  dump to reformat acsc strings into canonical
+       form (sorted, unique mapping).
+     * add  checks  in tic for inconsistent cursor-movement controls, and
+       for inconsistent printer-controls.
+     * add  special  case  to  _nc_infotocap (used by tic and infocmp) to
+       recognize   the   setaf/setab   strings  from  xterm+256color  and
+       xterm+88color,  and  provide  a  reduced  version which works with
+       termcap.
+
+  Terminal Database
+
+     * added entries:
+          + bterm terminfo entry, based on bogl 0.1.18
+          + cons25-debian entry
+          + eterm-color entry
+          + linux-16color
+          + mlterm+256color entry, for mlterm 3.0.0
+          + several screen-bce.xxx entries
+          + screen.Eterm terminfo entry
+          + vwmterm entry
+          + xterm-utf8 entry as a demo of the U8 feature
+     * updated/improved entries:
+          + use extended capabilities:
+               o add  U8 feature to denote entries for terminal emulators
+                 which  do  not support VT100 SI/SO when processing UTF-8
+                 encoding
+               o 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
+          + improvements based on new checks in tic:
+          +
+               o fill  in  no-parameter  forms of cursor-movement where a
+                 parameterized form is available
+               o fill  in  missing  cursor controls where the form of the
+                 controls is ANSI
+               o add parameterized cursor-controls to linux-basic
+               o modify  nsterm,  xnuppc  and  tek4115  to  make sgr/sgr0
+                 consistent
+               o change  several  terminfo entries to make consistent use
+                 of ANSI clear-all-tabs
+          + extend  ansi.sys  pfkey capability from kf1-kf10 to kf1-kf48,
+            moving   function   key   definitions   from   emx-base   for
+            consistency.
+          + correct   missing   final   'p'   in   pfkey   capability  of
+            ansi.sys-old.
+          + rename   atari   and  st52  terminfo  entries  to  atari-old,
+            st52-old, use newer entries from FreeMiNT.
+          + repurpose  gnome  terminfo  entries  as  vte, retaining gnome
+            variants  for  compatibility, but generally deprecating those
+            since  the  VTE library is what actually defines the behavior
+            of "gnome", etc., since 2003.
+          + improve  interix  smso  terminfo  capability by using reverse
+            rather than bold.
+          + correct  initc  capability  of  linux-c-nc end-of-range, make
+            similar change for dg+ccc and dgunix+ccc.
+          + update minix terminfo entry.
+          + updated nsterm* entries.
+          + remove unnecessary kcan assignment to ^C from putty.
+          + suppress  ncv  in  screen  and konsole-base entries, allowing
+            underline.
+          + change ncv and op capabilities in sun-color terminfo entry to
+            match Sun's entry for this.
+          + fix typo in rmso for tek4106 entry.
+          + improve acsc string for vt52, show arrow keys.
+          + add  hard-reset  for  rs2 to wsvt25 to help ensure that reset
+            ends the alternate character set.
+          + add ccc and initc capabilities to xterm-16color.
+
+Major bug fixes
+
+     * ncurses library
+          + wide character support
+               o modify length returned by getcchar to count the trailing
+                 null which is documented in X/Open.
+               o fix  an  infinite  recursion when adding a legacy-coding
+                 8-bit value using insch.
+               o improve  a  workaround in adding wide-characters, when a
+                 control  character  is found. The library uses unctrl to
+                 obtain a printable version of the control character, but
+                 was not passing color or video attributes.
+               o 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.
+               o fixes in wins_nwstr and related functions to ensure that
+                 special characters, i.e., control characters are handled
+                 properly with the wide-character configuration.
+               o 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.
+          + mouse
+               o 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.
+               o add  check  in mouse-driver to disable connection if GPM
+                 returns  a  zero,  indicating  that  the  connection  is
+                 closed.
+               o 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.
+          + miscellaneous
+               o improve  handling  of color-pairs embedded in attributes
+                 for the extended-colors configuration.
+               o add check for failure to open hashed-database needed for
+                 db4.6.
+               o 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.
+               o modify  declaration  of  cur_term  when broken-linker is
+                 used, but enable-reentrant is not, to match pre-5.7.
+               o correct limit-checks in derwin.
+               o remove  old  check  in mvderwin which prevented moving a
+                 derived  window  whose  origin happened to coincide with
+                 its parent's origin.
+               o correct  limit-checks  in newwin, to ensure that windows
+                 have nonzero size.
+               o modify  set_curterm  to make broken-linker configuration
+                 work with changes from 20090228.
+               o modify  wgetch to ensure it checks SIGWINCH when it gets
+                 an error in non-blocking mode.
+               o correct   limit-check   in   wredrawln,  accounting  for
+                 begy/begx values.
+               o fix   a   null-pointer   check   in  _nc_format_slks  in
+                 lib_slk.c, from 20070704 changes.
+               o correct  translation  of  "^"  in _nc_infotocap, used to
+                 transform terminfo to termcap strings.
+               o modify  _nc_wgetch  to check for a -1 in the fifo, e.g.,
+                 after  a  SIGWINCH,  and  discard  that  value, to avoid
+                 confusing application.
+     * other libraries
+          + correct   transfer  of  multicolumn  characters  in  multirow
+            field_buffer,  which  stopped at the end of the first row due
+            to filling of unused entries in a cchar_t array with nulls.
+          + correct buffer-size after internal resizing of wide-character
+            set_field_buffer, broken in 20081018 changes.
+          + correct  layout  of  working  window  used to extract data in
+            wide-character configured by set_field_buffer
+
+Portability
+
      * configure script:
           + new options:
 
-              --disable-big-strings
-                      control  whether static string tables are generated
-                      as   single   large  strings  (to  improve  startup
-                      performance), or as array of individual strings.
-
-              --disable-relink
-                      control   whether  shared  libraries  are  relinked

-
-              --disable-tic-depends
-                      make   explicit  whether  tic  library  depends  on
-                      ncurses/ncursesw library.
-
-              --enable-mixed-case
-                      override   the  configure  script's  check  if  the
-                      filesystem   supports  mixed-case  filenames.  This
-                      allows  one  to  control  how the terminal database
-                      maps to the filesystem. For filesystems that do not
-                      support   mixed-case,  the  library  uses  generate
-                      2-character (hexadecimal) codes for the lower-level
-                      of the filesystem terminfo database
-
-              --enable-reentrant
-                      builds  a  different  flavor of the ncurses library
-                      (ncursest)  which  improves  reentrant  use  of the
-                      library  by  reducing  global  and static variables
-                      (see  the  "--with-pthread" option for the threaded
-                      support).
-
-              --enable-weak-symbols
-                      use  weak-symbols  for  linking to the POSIX thread
-                      library,  and  use  the same soname for the ncurses
-                      shared  library  as the normal library (caveat: the
-                      ABI is for the threaded library, which makes global
-                      data accessed via functions).
-
-              --with-pthread

+     * packaging:

+               o modify  adacurses-config to look for ".ali" files in the
+                 adalib directory.
+               o correct  install  for  the  Ada95  tree,  which  omitted

+               o generate manpages for the *-config scripts, adapted from
+                 help2man.
+               o modify   install-rule  for  manpages  so  that  *-config

+                 first item in a possibly colon-separated list.
+          + other packaging issues
+               o add make-tar.sh scripts to Ada95 and test subdirectories
+                 to help with making those separately distributable.
+               o add  Ada95/configure  script, to use in tar-file created
+                 by Ada95/make-tar.sh.
+               o remove   tar-copy.sh   and   related  configure/Makefile
+                 chunks,  since  the Ada95 binding is now installed using
+                 rules in Ada95/src.
+     * cross-compiling:
+          + improve  configure  checks  for  location  of tic and infocmp
+            programs  used  for  installing  database  and for generating
+            fallback data, e.g., for cross-compiling.
+          + modify  #define's  for  build-compiler  to  suppress  cchar_t
+            symbol  from  compile  of  make_hash and make_keys, improving
+            cross-compilation of ncursesw.
+          + 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.
+          + correct cross-compiling configure check for CF_MKSTEMP macro,
+            by adding a check cache variable set by AC_CHECK_FUNC.
+     * library dependencies:
+          + revise  wadd_wch  and  wecho_wchar to eliminate dependency on
+            unctrl.
+          + 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.
+     * building the Ada95 tree:
+          + changes to use gnatmake project files in the Ada95 tree.
+          + add/use   configure  check  to  turn  on  project  rules  for
+            Ada95/src.
+          + old   gnatmake   (3.15)  does  not  produce  libraries  using
+            project-file;  work  around  by  adding  script  to  generate
+            alternate makefile.
+          + 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.
+          + add test_make / test_clean / test_install rules in Ada95/src
+          + change    install-path    for    adainclude    directory   to
+            /usr/share/ada (was /usr/lib/ada).
      * other configure/build issues:
-          + build-fixes for LynxOS
-          + modify  shared-library  rules  to  allow  FreeBSD  3.x to use
-            rpath.
-          + build-fix for FreeBSD "contemporary" TTY interface.
-          + build-fixes for AIX with libtool.
-          + build-fixes for Darwin and libtool.
-          + modify BeOS-specific ifdef's to build on Haiku.
-          + corrected  gcc  options  for  building  shared  libraries  on
-            Solaris and IRIX64.
-          + change  shared-library  configuration for OpenBSD, make rpath
-            work.
-          + build-fixes for using libutf8, e.g., on OpenBSD 3.7
-          + add   "-e"  option  in  ncurses/Makefile.in  when  generating
-            source-files  to  force earlier exit if the build environment
-            fails unexpectedly.
-          + add support for shared libraries for QNX.
-          + change  delimiter  in  MKlib_gen.sh from '%' to '@', to avoid
-            substitution  by  IBM xlc to '#' as part of its extensions to
-            digraphs.
-     * library:
-          + rewrite  wrapper  for  wcrtomb(),  making it work on Solaris.
-            This  is  used in the form library to determine the length of
-            the buffer needed by field_buffer.
-          + add/use  configure  script  macro  CF_SIG_ATOMIC_T,  use  the
-            corresponding type for data manipulated by signal handlers.
-          + set locale in misc/ncurses-config.in since it uses a range
-          + disable  GPM  mouse  support  when  $TERM  does not happen to
-            contain  "linux",  since  Gpm_Open()  no  longer  limits  its
-            assertion  to  terminals  that  it might handle, e.g., within
-            "screen" in xterm.
-          + reset mouse file-descriptor when unloading GPM library.
+          + make CCHARW_MAX value configurable, noting that changing this
+            would   change   the   size   of   cchar_t,   and   would  be
+            ABI-incompatible.
+          + improve  comparison of program-names when checking for linked
+            flavors such as "reset" by ignoring the executable suffix.
+          + drop mkdirs.sh, use "mkdir -p".
+          + drop  misc/ncu-indent  and misc/jpf-indent; they are provided
+            by an external package [3]cindent.
+          + change  makefiles  to  use  $ARFLAGS  rather  than  $AR_OPTS,
+            provide  a  configure check to detect whether a "-" is needed
+            before "ar" options.
+          + modify   CF_DISABLE_LEAKS   configure   macro   so  that  the
+            --enable-leaks option is not the same as --disable-leaks.
+          + improve    configure   script   macros   CF_HEADER_PATH   and
+            CF_LIBRARY_PATH  by adding CFLAGS, CPPFLAGS and LDFLAGS, LIBS
+            values to the search-lists.
+          + 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.
+          + 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  symbolic  links  in makefiles by using "-f"
+            option  if it is supported, to eliminate temporary removal of
+            the target
+          + add  a  configure-time  check  to  pick  a suitable value for
+            CC_SHARED_OPTS for Solaris.
+          + add  -shared option to MK_SHARED_LIB when -Bsharable is used,
+            for  *BSD's,  without which "main" might be one of the shared
+            library's dependencies.
+          + modify  configure  script  to allow building shared libraries
+            with gcc on AIX 5 or 6.
+          + suppress  configure check for static/dynamic linker flags for
+            gcc on Solaris 10, since gcc is confused by absence of static
+            libc,  and  does  not  switch  back  to  dynamic  mode before
+            finishing the libraries.
+          + suppress  configure check for static/dynamic linker flags for
+            gcc on Darwin.
+          + modify  misc/run_tic.in  to  create parent directory, in case
+            this is a new install of hashed database.
+          + 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.
      * test programs:
-          + update  test  programs to build/work with various UNIX curses
-            for comparisons.
+          + add test/demo_terminfo, for comparison with demo_termcap.
+          + improve test/ncurses.c 'F' test, show combining characters in
+            color.
+          + fix logic for 'V' in test/ncurses.c tests f/F.
+          + improve  test/ncurses.c 'a test to put mouse droppings in the
+            proper window.
+          + modify  ncurses  'F'  test  to  demo wborder_set with colored
+            lines.
+          + modify ncurses 'f' test to demo wborder with colored lines.
+          + improve   test/ncurses.c   'a'   test,   using   unctrl  more
+            consistently to display meta-characters.
+          + correct  use  of  key_name  in test/ncurses.c 'A' test, which
+            only displays wide-characters, not key-codes since 20070612.
+          + add  test/clip_printw.c  to  illustrate  how  to  use  printw
+            without wrapping.
+          + modify  test-programs,  e.g,.  test/view.c, to address subtle
+            differences   between  Tru64/Solaris  and  HPUX/AIX  getcchar
+            return values.
+          + 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
+          + add test/xterm-256color.dat
+          + modify  test  programs  to allow them to be built with NetBSD
+            curses.
+          + fixes for test programs to build/work on HPUX and AIX, etc.

+dnl Look for the SVr4 curses clone 'ncurses' in the standard places, adjusting
+dnl the CPPFLAGS variable so we can include its header.
+dnl
+dnl The header files may be installed as either curses.h, or ncurses.h (would
+dnl be obsolete, except that some packagers prefer this name to distinguish it
+dnl from a "native" curses implementation).  If not installed for overwrite,
+dnl the curses.h file would be in an ncurses subdirectory (e.g.,
+dnl /usr/include/ncurses), but someone may have installed overwriting the
+dnl vendor's curses.  Only very old versions (pre-1.9.2d, the first autoconf'd
+dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
+dnl the header.
+dnl
+dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
+dnl is already in the include-path, don't even bother with this, since we cannot
+dnl easily determine which file it is.  In this case, it has to be <curses.h>.
+dnl
+dnl The optional parameter gives the root name of the library, in case it is
+dnl not installed as the default curses library.  That is how the
+dnl wide-character version of ncurses is installed.

+dnl --------------
+dnl --------------
+dnl Attempt to determine the appropriate CC/LD options for creating a shared
+dnl library.
+dnl
+dnl Note: ${LOCAL_LDFLAGS} is used to link executables that will run within the
+dnl build-tree, i.e., by making use of the libraries that are compiled in ../lib
+dnl We avoid compiling-in a ../lib path for the shared library since that can
+dnl lead to unexpected results at runtime.
+dnl ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared libraries
+dnl are compiled in ../../lib
+dnl
+dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
+dnl to install symbolic links to the rel/abi versions of shared libraries.
+dnl
+dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
+dnl version when making symbolic links.
+dnl
+dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
+dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
+dnl (ex: libncurses.so.<ver>).
+dnl
+dnl Some loaders leave 'so_locations' lying around.  It's nice to clean up.
