We already have backward compatibility symlinks for ncurses libraries and pkg-config files (when built in unicode/wide mode). The last bit is to add a symlink from ncurses5-config to ncursesw5-config, which is what this commit does.

longDescription = ''
|
|
The Ncurses (new curses) library is a free software emulation of
|
|
curses in System V Release 4.0, and more. It uses Terminfo
|
|
format, supports pads and color and multiple highlights and
|
|
forms characters and function-key mapping, and has all the other
|
|
SYSV-curses enhancements over BSD Curses.
|
|
|
|
The ncurses code was developed under GNU/Linux. It has been in
|
|
use for some time with OpenBSD as the system curses library, and
|
|
on FreeBSD and NetBSD as an external package. It should port
|
|
easily to any ANSI/POSIX-conforming UNIX. It has even been
|
|
ported to OS/2 Warp!
