- The default C++ allocator is non-generic and optimized for
multithreaded applications.
If I recall correctly, OpenOffice.org relies on libstdc++.
http://gcc.gnu.org/ml/libstdc++/2005-02/msg00061.html
- GCC 4.0 offers the possibility of defining symbols as "hidden",
minimizing the overhead of shared object dynamic loading.
There's some information on how this is useful here:

A full list of the great new features is on:
