+ The symbols beginning NCURSES_ or USE_ are configuration choices.
+ A few of the former can be overridden by applications at compile-time.
+ Most of the others correspond to configure-script options (or checks
+ by the configure-script for features of the system on which it is built).
+
+ These symbols can be overridden by applications at compile-time:
+ NCURSES_NOMACROS suppresses macro definitions in favor of functions
+ NCURSES_WATTR_MACROS suppresses wattr_* macro definitions
+ NCURSES_WIDECHAR is an alternative for declaring wide-character functions.
+
+ These symbols are used only when building ncurses:
+ NCURSES_ATTR_T
+ NCURSES_FIELD_INTERNALS
+ NCURSES_INTERNALS
+
+ These symbols are set by the configure script:
+ NCURSES_ENABLE_STDBOOL_H
+ NCURSES_EXPANDED
+ NCURSES_EXT_COLORS
+ NCURSES_EXT_FUNCS
+ NCURSES_EXT_PUTWIN
+ NCURSES_NO_PADDING
