1961 dnl Look for the SVr4 curses clone 'ncurses' in the standard places, adjusting

1964 dnl The header files may be installed as either curses.h, or ncurses.h (would
1965 dnl be obsolete, except that some packagers prefer this name to distinguish it
1966 dnl from a "native" curses implementation). If not installed for overwrite,
1967 dnl the curses.h file would be in an ncurses subdirectory (e.g.,
1968 dnl /usr/include/ncurses), but someone may have installed overwriting the
1969 dnl vendor's curses. Only very old versions (pre-1.9.2d, the first autoconf'd
1970 dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
1973 dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
1974 dnl is already in the include-path, don't even bother with this, since we cannot
1975 dnl easily determine which file it is. In this case, it has to be <curses.h>.
1977 dnl The optional parameter gives the root name of the library, in case it is
1978 dnl not installed as the default curses library. That is how the
1979 dnl wide-character version of ncurses is installed.
