+ improve description in INSTALL of the --with-versioned-syms option.
+ add combination of --with-hashed-db and --with-ticlib to
configurations for ".map" files (report by Werner Fink).
+ 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.
+ 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).
+ improved ".map" files by generating them with a script that builds
ncurses with several related configurations and merges the results.
A further refinement is planned, to make the tic- and tinfo-library
symbols use the same versions across each of the four configurations
which are represented (reports by Sven Joachim, Werner Fink).
+ 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.
