+ updated ".map" files so that each symbol that may be shared across
the different library configurations has the same label. Some
review is needed to ensure these are really compatible.
+ modify MKlib_gen.sh to work around change in development version of
gcc introduced here:
https://gcc.gnu.org/ml/gcc-patches/2014-06/msg02185.htmlhttps://gcc.gnu.org/ml/gcc-patches/2014-07/msg00236.html
(reports by Marcus Shawcroft, Maohui Lei).
+ improved configure macro CF_SUBDIR_PATH, from lynx changes.
+ 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.
