  The symbols beginning NCURSES_ or USE_ are configuration choices.

  Most of the others correspond to configure-script options (or checks

  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
