C linkers don't normally work that way. If they did, you wouldn't generally get 
multiple definition errors and the like. So, while it might be theoretically 
reasonable, it might be too much of a change from how linking normally works. 
And since it would ultimately just be optlink which would work that way, would 
it really be a good idea anyway? As soon as you tried your code with another 
linker - e.g. by compiling on Liunx - it would fail.
