I agree this is a good thing but it should be noted that to some extend
there are problems with -fvisibility=hidden in GCCs before July 1,  
2006's
mainline (at least in C++).  There are other issues with it even in  
today's
mainline GCC that have not been fixed yet.  If someone wants more  
details
at the problems in GCC with this option, I can point them to the bug  
reports.

Thanks,
