Up-to-date instructions on Linux based cross-compiler to Win32

[Marco Leise]

As the topic suggests, I'm looking for instructions to get a cross-compiler working on Linux and the ones in the Wiki are fairly outdated, referring to old versions of D2 and GCC.

The compiler actually builds, but it cannot build Phobos, with these lines of errors:
/home/marco/Entwicklung/D/gdc/dev/gcc-4.6.2/windows/./gcc/gdc -B/home/marco/Entwicklung/D/gdc/dev/gcc-4.6.2/windows/./gcc/ -L/home/marco/Entwicklung/D/gdc/dev/gcc-4.6.2/windows/i686-mingw32/winsup/mingw -L/home/marco/Entwicklung/D/gdc/dev/gcc-4.6.2/windows/i686-mingw32/winsup/w32api/lib -isystem /home/marco/Entwicklung/D/gdc/dev/gcc-4.6.2/winsup/mingw/include -isystem /home/marco/Entwicklung/D/gdc/dev/gcc-4.6.2/winsup/w32api/include -B/usr/i686-mingw32/bin/ -B/usr/i686-mingw32/lib/ -isystem /usr/i686-mingw32/include -isystem /usr/i686-mingw32/sys-include -Wall -g -frelease -O2  -nostdinc -pipe -fdeprecated -I ../../../libphobos -I ./i686-mingw32  -fintfc-file=import/core/sys/windows/dbghelp.di -fsyntax-only ../../../libphobos/core/sys/windows/dbghelp.d
