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.
ncurses 5.7 was released in 2008 and is now 9 years old. Why
is OpenBSD still using such an ancient version?

I'm a bit wary of this because we've found in the past that
defining _XOPEN_* defines breaks compilation with some
C libraries which assume that if you define _XOPEN_whatever
it means "only that X/Open stuff and no OS-specific extras",
and we depend on the OS-specific extras.
That said, I did a test compile on OSX, which was the
one that had trouble previously, so this may be OK. I think
I'd rather leave it until after 2.11 releases, though.
I am not in a rush for 2.11. This and the other issues being
mentioned are not new. Thanks for the consideration of the diff
at all.
