GCC 4.6

[Caligo]

I've been doing a lot of coding in D in the past few weeks, and one
thing I've noticed is that performance is not great.  Surprisingly,
DMD generated binaries perform worse than GDC's, but even GDC is
lagging behind equivalent code written in C++ and compiled with G++.
Are we to expect performance to improve as more work is done on GDC?

Another thing that's bothering me is that there is currently only one
active developer working on GDC.
