Subject: Don't bail out if configure (without --with-curses) does not find libcurses.
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=040c84343b09924bbd96902f502cb2179d8f63a7;p=gnushogi.git

Don't bail out if configure (without --with-curses) does not find libcurses.

Only fail when --with-curses was requested and libcurses cannot be found.
