The actual functionality is untested, but without this patch,
ytalk just seg-faults as soon as readdress appears in a configuration
file.
Problem reported as random segfaults by todd@, nice common debugging
session :)
Porters: please make sure you use bsd.port.mk 1.75 or later when
updating ports. That version of the makefile adds all sums. Previous
versions of the makefile will still work for people installing ports.
