In general, I suggest turning ZeroLink off, only turning it on to focus on
a particular problem. ZeroLink is bad when you're just getting the basic
structure off the ground, because it postpones the detection of "stupid
programmer" types of linking errors.
ZeroLink is useful when you're focusing in on one area of a program whose
overall structure is already known to be good. That is, if you've already
done one or more compile and link builds with ZeroLink off, then you know
that all unresolved symbols have been resolved, duplicates eliminated, and
so on. Once that's done, then turn on ZeroLink to focus on one particular
area where rapid recompile-and-run is desired.
So it's really a question of focus: broad or narrow, and tradeoffs:
recompile-time vs. link-blunder detection.
