              How to install Ncurses/Terminfo on your system

+    --disable-wattr-macros
+       The 6.0 ABI adds support for extended colors and for extended mouse.
+       The former is a noticeable problem when developers inadvertantly
+       compile using the ncurses6 header files and link with an ncurses5
+       library, because the wattr* macros use a new field in the WINDOW
+       structure.  These macros are used in several applications.
+
+       Since ncurses provides an actual function for each of these macros,
+       suppressing them from the curses.h header allows the ncurses5 libraries
+       to be used in most applications.
+
+       NOTE: The extended colors also are used in the cchar_t structure, but
+       fewer applications use that.
+
+       NOTE: This workaround does not help with mismatches in the ncurses
+       mouse version.  The extended mouse feature uses one less fewer bit for
+       each button, so that only the first button will work as expected with
+       a mismatch between header and library.  Again, most applications will
+       work, since most use only the first button.

        For testing, compile-in assertion code.  This is used only for a few
        places where ncurses cannot easily recover by returning an error code.
