Dang, I thought this was fixed some days ago... guess not.

Sezero also provides his GCC 4.4 builds, right
here<http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/sezero_20101003/>.
They do indeed work around the assistant and browser demo crash. The UI
issue can be helped by configuring with "-qt-style-windowsxp
-qt-style-windowsvista" (this is needed because Qt's configure does not
detect the required headers with mingw-w64 installs). You could also enable
phonon by adding "-phonon" which builds the DirectX backend using the
mingw-w64 DirectX headers (from the Wine project).

This might be, but a lot of projects that aren't written with x64 Windows in
mind have such code and produce these warnings. It surely might be related
to the crash, I haven't looked into it yet. Feel free to experiment :)

Also: The 4.7 branch is equally functional under mingw-w64, no need to use
the unstable master branch.

The modern datacenter depends on network connectivity to access resources
and provide services. The best practices for maximizing a physical server's
connectivity to a physical network are well understood - see how these
rules translate into the virtual world?
