For wcscpy yes. Who uses wcscpy? Optimizing it is a worthless time sink.

strcpy optimization might be worth keeping, as it's used so much more. 
Measurements of real programs would help decide. In the meantime inertia 
suggests that when in doubt, leave it alone.

For strlcpy it's an easy call: don't optimize unless realistic 
benchmarks show it's a win.
