[Qemu-devel] [PATCH] configure: Fix curses probe for older ncurses

From: Brad Smith
Subject: [Qemu-devel] [PATCH] configure: Fix curses probe for older ncurses
Date: Sun, 26 Nov 2017 16:13:57 -0500
User-agent: Mutt/1.9.1 (2017-09-22)

Fix the curses probe with older ncurses (.e.g. 5.7, as used by OpenBSD).

ncurses 5.7 requires _XOPEN_SOURCE_EXTENDED to be defined for WACS_* constants.
