Title: GCC 4.6.3 is released.

GCC 4.6.3 is released. http://gcc.gnu.org/gcc-4.6/
I updated gcc tarball version from 4.6.2 to 4.6.3.
And, I enable Link Time Optimization option.
LTO was disabled because of this MacPorts issue ( http://lists.macosforge.org/pipermail/macports-dev/2011-March/014278.html) . However, MacPorts gcc46 PortFile now enables LTO ( https://trac.macports.org/browser/trunk/dports/lang/gcc46/Portfile ). This is the reason why I enable LTO.
