[PATCH] aclocal.m4: Enable configure to detect the presence of ncurses on OpenBSD 3.2

[Pavel Tsekov <ptsekov gmx net>]

Hello,

OpenBSD 3.2 (I think also earlier versions, but cannot confirm) comes 
with ncurses as the default screen library. However it is installed as 
/usr/lib/libcurses.so, there is no libncurses in OpenBSD by default.

This patch alters the macro MC_WITH_NCURSES to properly handle this 
situation - it first tries to find the 'has_colors' symbol in libncurses 
and then fallbacks to libcurses.

Please check the patch for possible errors, since I'm not good in auto* 
stuff.

Thanks!
