+ improve man/curs_inwstr.3x, correct end-logic for lib_inwstr.c
(report by Midolikawa H).
+ fix typo in a few places for "improvements" (patch by Sven Joachim).
+ clear the other half of a double-width character on which a line
drawing character is drawn.
+ make test/ncurses.c "s" test easier to understand which subtests are
available; add a "S" wide-character overlap test-screen.
+ modify test/ncurses.c C/c tests to allow for extended color pairs.
+ add endwin() call in error-returns from test/ncurses.c omitted in
recent redesign of its menu (cf: 20170923).
+ improve install of hashed-db by removing the ".db" file as done for
directory-tree terminal databases.
+ repair a few overlooked items in include/ncurses_defs from recent
port/refactoring of test-programs (cf: 20170909).
+ add test/padview.c, to compare pads with direct updates in view.c
+ improve CF_GCC_VERSION to work around Debian's customization of gcc
--version message.
+ improve configure macros as done in byacc:
+ drop 2.13 compatibility; use 2.52.xxxx version only since EMX port
has used that for a while.
+ add 3rd parameter to AC_DEFINE's to allow autoheader to run, i.e.,
for experimental use.
+ remove unused configure macros.
+ modify configure script and makefiles to quiet new autoconf warning
for LIBS_TO_MAKE variable.
+ modify configure script to show $PATH_SEPARATOR variable.
+ update config.guess, config.sub
+ update autoconf patch to 2.52.20120811, adding --datarootdir
(prompted by discussion with Erwin Waterlander).
+ improve description of --enable-reentrant option in README and the
INSTALL file.
+ add nsterm-256color, make this the default nsterm -TD
+ remove bw from nsterm-bce, per testing with tack -TD
+ update release notes, for 5.8.
+ regenerated html manpages.
+ change open() in _nc_read_file_entry() to fopen() for consistency
with write_file().
+ modify misc/run_tic.in to create parent directory, in case this is
a new install of hashed database.
+ fix typo in Ada95/mk-1st.awk which causes error with original awk.
+ add cons25-debian entry (patch by Brian M Carlson, Debian #607662).
+ configure script rpath fixes from xterm #269.
+ workaround for cygwin's non-functional features.h, to force ncurses'
configure script to define _XOPEN_SOURCE_EXTENDED when building
wide-character configuration.
+ build-fix in run_tic.sh for OS/2 EMX install
+ add cons25-debian entry (patch by Brian M Carlson, Debina #607662).
+ 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).
+ fix several places in configure script using ${variable-value} form.
+ modify configure macro CF_LDFLAGS_STATIC to accommodate some loaders
which do not support selectively linking against static libraries
(report by John P. Hartmann)

+ correct a typo in mk-1st.awk (patch by Gabriele Balducci)
(cf: 20100724)
+ 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.
+ correct use of terminfo capabilities for initializing soft-keys,
broken in 20090509 merging.
+ modify wgetch() to ensure it checks SIGWINCH when it gets an error
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).
