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

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