blackened core-dumps during screen initialisation in -current.
	Some investigating with gdb shows that pointers are being
	truncated to 32-bits.  Re-compiling blackened with '-Wall'
	reveals large numbers of "implicit declaration of function"
	warnings as well as several int/long mismatches in printf()s.
	
	Since the current tarball is 6 years old, has no homepage,
	no FreeBSD maintainer and the IRC channel quoted for support
	doesn't work, I'd suggest that this is abandonware and the
	port be deprecated and scheduled for deorbit.  Given the age
	and number of coding errors revealed with '-Wall', it would
	not surprise me if there were secutiry issues as well.  Note
	that I am not currently in a position to become maintainer.

Fix: 

Either correct coding errors revealed by -Wall or remove from
	ports.
How-To-Repeat: 	Run 64-bit blackened executable on 64-bit -current system.
