Onto compiler talk I see ;).

I hear PCC is a more likely candidate in the near but not-near future. 
Also is it true that FreeBSD isn't adopting GCC 4.3.X+ because of 
licensing discrepancies? There is a big performance gap between gcc 
4.2.1 and gcc 4.3.X that makes FreeBSD look bad in the useless 
benchmarks by phoronix.
