+ modify util.c to work better with old versions of ncurses:
+ suppress use of wchgat() before fix in 20060715 which is needed
for simple shadow manipulation used here in 2011/06/30 (report
by xDog Walker).
+ add a null-pointer check in dlg_print_scrolled()
+ fix a regression in dlg_getc() introduced by changes to intercept
F1 for help-popup (report by xDog Walker).
2011/06/30
+ correct license statement for prgbox.c (Debian #632198).
+ correct layout when "--colors" is used, by discounting characters in
the escape sequences from the column counts (report by xDog Walker).
+ modify dlg_checklist() so that only one item in the list can
initially be selected (report by xDog Walker).
+ add/use macro dlg_enter_buttoncode() to improve implementation of
"--nook" option (report by xDog Walker).
+ add option "--no-nl-expand" to suppress the conversion of "\n"
strings into newlines (request by xDog Walker).
+ modify LIB_CREATE symbol in makefile.in to include the library
dependencies such as ncurses. This is needed when dynamically
loading the library (report/analysis by xDog Walker).
+ modify dlg_exit_label() to suppress the Cancel button, for
consistency.
+ modify dlg_exit_label() to honor the --nook option, except when there
is no other button, e.g., the help-button.
+ modify dlg_exit_buttoncode() so that it returns the proper code for
help-button (report by xDog Walker).
+ correct loop limit when processing "--column-separator" (report by
xDog Walker).
+ modify handling of "--version" and "--help" to ensure that they are
processed, and exit before widgets. Separate "--print-version"
from "--version", allowing its output to be interspersed with
widget output (report by xDog Walker).
+ correct a few places where "--version" or "--help" options went
always to stdout rather than allowing redirection with the "--stderr"
option (report by xDog Walker).
+ improve repainting after erasing a widget and its shadow.
+ add "--hline" and "--hfile" options for compatibility with FreeBSD
dialog (request by Devin Teske).
+ add dialog version message when opening a trace file (request by
xDog Walker).
+ show filename of rc-file in traces.
+ add piped-in data for gauge widget to traces.
+ add entrypoints to gauge widget, for allocating, updating and freeing
the widget (adapted from patch by Stephen Hurd).
+ fix a reference to freed memory in the gauge widget.
+ fix --no-mouse option by actually closing the mouse (report by
xDog Walker).
+ add sk.po from
http://translationproject.org/latest/dialog/
+ limit Solaris xpg4 portability fix for redefinition of ERR to cover
the specific value found in <sys/regset.h>, in case an application
includes dialog.h after curses.h (FreeBSD #156601, report by Jaakko
Heinonen, Stephen Hurd).
+ updated configure macros:
+ CF_CURSES_CPPFLAGS,
+ CF_CURSES_LIBS, make checks for special libraries on hpux10 and
sunos4 optional
+ CF_CURSES_FUNCS, workaround for bug in gcc 4.2.1 (FreeBSD 8.1)
which caused part of test program to be omitted, i.e., when it saw
two return-statements in a row it omitted the _first_ one. Also
add expression to pointer check to help FreeBSD's linker decide it
should be validated. Just an assignment was not enough. Also, add
check for unctrl.h
+ CF_CURSES_HEADER, change order for curses.h / ncurses.h pairs to
put ncurses.h first, which will tend to provide the same #define's
as in CF_NCURSES_HEADER (report by Dennis Preiser).
+ CF_CURSES_TERM_H, modify to avoid spurious check for
<curses.hterm.h> if there is no ncurses version. Look for
ncurses's term.h anyway, to work around breakage by packagers who
separate ncurses' header files.
+ CF_DISABLE_RPATH_HACK, fix garbled message
+ CF_LD_RPATH_OPT, add mirbsd
+ CF_MAKEFLAGS, filter out GNU make's entering/leaving messages.
This only appeared when using the macro in a dpkg script, though it
should have in other cases.
+ CF_RPATH_HACK, add a check for libraries not found, e.g., from
suppressed functionality of gcc in linking from /usr/local/lib, and
add a -L option to help work around this.
+ CF_XOPEN_SOURCE, workaround for cygwin to get ncurses' configure
script to define _XOPEN_SOURCE_EXTENDED (cygwin's features.h
doesn't do anything, so it needs a crutch).
+ updated config.guess, config.sub
