OK, the problem is easy enough to understand -- it appears that OS X 10.9 is defining 'strlcpy' whereas earlier versions did not. This causes a conflict with my util function of the same name. Need to figure out the idiomatic way of detecting this.

Ok, I'm not much of a C person, but if there is something I can do to assist let me know.
