1962 dnl be obsolete, except that some packagers prefer this name to distinguish it
1963 dnl from a "native" curses implementation). If not installed for overwrite,
1964 dnl the curses.h file would be in an ncurses subdirectory (e.g.,
1965 dnl /usr/include/ncurses), but someone may have installed overwriting the
1966 dnl vendor's curses. Only very old versions (pre-1.9.2d, the first autoconf'd
1967 dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
1970 dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
1971 dnl is already in the include-path, don't even bother with this, since we cannot
1972 dnl easily determine which file it is. In this case, it has to be <curses.h>.
1974 dnl The optional parameter gives the root name of the library, in case it is
1975 dnl not installed as the default curses library. That is how the
1976 dnl wide-character version of ncurses is installed.
