- What's so cool about GCC 4.0?
GCC 4.0 includes:
- new intermediate languages that allow for new/better optimizations
http://gcc.gnu.org/projects/tree-ssa/
As part of this, this allows for better compile and run-time memory
checking and overflow protection.
- better and more complete Java support
- Fortran 95 support
- The default C++ allocator is non-generic and optimized for multithreaded applications.
If I recall correctly, OpenOffice.org relies on libstdc++.

- 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:
