              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.
