It shouldn't, as long as the code is fairly well behaved.  We're starting to 
use this for OpenOffice.org as well, any large C++ app can greatly benefit from 
this option because the rather un-optimized dynamic linker doesn't have to load 
and resolve as many symbols at run-time.  You should get link-time errors if 
symbols that aren't explicitly marked visible are needed by some other part of 
the program.
