--- Comment #8 from Costas Argyris <costas.argyris at gmail dot com> --- Are you building the cross-compiler itself or just using an existing cross-compiler to build for the windows host? You may have to build the cross-compiler first from the latest gcc sources, and then use that newly-built cross-compiler to build the same gcc sources into a windows-hosted compiler.
