The GNU Compiler Collection version 4.6.0 has been released.

GCC 4.6.0 is a major release, containing substantial new functionality
not available in GCC 4.5.x or previous GCC releases.

The “link-time optimization” framework introduced in GCC 4.5.0 has been
significantly improved in this release, it is now possible to compile
very large applications like Mozilla or GCC itself with LTO.
GCC can now partially inline functions, inlining just hot short path
to exit and keeping the rest of the function out of line.
Support for the upcoming C++0x standard has been notably improved,
Fortran 2003 and 2008 has been greatly extended and many other frontends
undergone substantial changes as well.
Many other improvements have been added and more than thousand of bugs
have been fixed in various parts of the compiler collection.
