dnl LIBDIR is used to find the intl libraries. If empty,

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

|
dnl the CPPFLAGS variable so we can include its header.
|
|
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
