+ + fix a few problems reported by Coverity.
+ + fix comparison against "/usr/include" in misc/gen-pkgconfig.in
+ (report by Daiki Ueno, Debian #790548, cf: 20141213).
+
+20150627
+ + modify configure script to remove deprecated ABI 5 symbols when
+ building ABI 6.
+ + add symbols _nc_Default_Field, _nc_Default_Form, _nc_has_mouse to
+ map-files, but marked as deprecated so that they can easily be
+ suppressed from ABI 6 builds (Debian #788610).
+ + comment-out "screen.xterm" entry, and inherit screen.xterm-256color
+ from xterm-new (report by Richard Birkett) -TD
+ + modify read_entry.c to set the error-return to -1 if no terminal
+ databases were found, as documented for setupterm.
+ + add test_setupterm.c to demonstrate normal/error returns from the
+ setupterm and restartterm functions.
+ + amend cleanup change from 20110813 which removed redundant definition
+ of ret_error, etc., from tinfo_driver.c, to account for the fact that
+ it should return a bool rather than int (report/analysis by Johannes
+ Schindelin).
+
+20150613
+ + fix overflow warning for OSX with lib_baudrate.c (cf: 20010630).
+ + modify script used to generate map/sym files to mark 5.9.20150530 as
+ the last "5.9" version, and regenerated the files. That makes the
+ files not use ".current" for the post-5.9 symbols. This also
+ corrects the label for _nc_sigprocmask used in when weak symbols are
+ configured for the ncursest/ncursestw libraries (prompted by
+ discussion with Sven Joachim).
+ + fix typo in NEWS (report by Sven Joachim).
