This was a request from Qt users to be able to build Qt (including webkit) with mingw 64 bits. It can be found here (http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/sezero_20100212/mingw-w64-bin_x86_64-mingw_20100212_sezero.zip/download). It is not yet released but we'd like to be one step ahead. The patch is pretty harmless and is mostly about avoiding casting pointers to int or long (which are 32 bits on mingw).
