+ + fixes for configure/build using clang on OSX (prompted by report by
+ William Gallafent).
+ + do not redefine "inline" in ncurses_cfg.h; this was originally to
+ solve a problem with gcc/g++, but is aggravated by clang's misuse
+ of symbols to pretend it is gcc.
+ + add braces to configure script to prevent unwanted add of
+ "-lstdc++" to the CXXLIBS symbol.
+ + improve/update test-program used for checking existence of stdc++
+ library.
+ + if $CXXLIBS is set, the linkage test uses that in addition to $LIBS
+
+20150905
+ + add note in curs_addch.3x about line-drawing when it depends upon
+ UTF-8.
+ + add tic -q option for consistency with infocmp, use it to suppress
+ all comments from the "tic -I" output.
+ + modify infocmp -q option to suppress the "Reconstructed from"
+ header.
+ + add infocmp/tic -Q option, which allows one to dump the compiled
+ form of the terminal entry, in hexadecimal or base64.
+
+20150822
+ + sort options in usage message for infocmp, to make it simpler to
+ see unused letters.
+ + update usage message for tic, adding "-0" option.
+ + documented differences in ESCDELAY versus AIX's implementation.
+ + fix some compiler warnings from ports.
+ + modify --with-pkg-config-libdir option to make it possible to install
+ ".pc" files even if pkg-config is not found (adapted from patch by
+ Joshua Root).
