Which compiler should be used for a x64 build?

kdesettings-example.bat suggests "mingw4", so effectively "mingw64".

I get problems in 
\kderoot\emerge\portage\dev-util\msys\msys2\msys2-20110627.py:

compiler.isX86() is not defined.
EmergeStandardDirs is not defined.

Should I be using MS Visual Studio instead? Which? 2010?
