How to install Ncurses/Terminfo on your system
---------------------------------------------------------------------
list documented in X/Open. ncurses provides varargs support for this
function. Use --disable-tparm-varargs to disable this support.
+ --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.

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