I'm afraid it involves a bit more than that. By default gcc 3 and earlier 
export all symbols, and symbols need to be "unexported" separately. If there 
was a PRIVATE macro that marked all non PUBLIC funcions and data, then under 
gcc 3 you could be able to define PRIVATE as 
__attribute__(visibility("hidden")), which would do the trick.

All other workarounds I'm aware of require gcc 4 or gcc 3+patches.
