Thanks Kai. Yes, it explains it very nicely. Now it is all clear.

We have this in our FAQ AFAIR. But once again, never - and I mean NEVER - use the executable you find in <sysroot>/<target>/bin. Only use the variant in <sysroot>/bin folder. In your case the later is the proper one (bin\x86_64-w64-mingw32-g++.exe). The other in <sysroot>/<target>/bin (in your case x86_64-w64-mingw32/bin/g++.exe) is for internal use of some build-tools. I repeat myself here. Never, really never call these executables directly!. The target-prefix before the gcc-tool is caused by the fact that you are using a cross-compiler. To control the bitness of target is done via the switches -m32/-m64. Of course you need to make sure that your used toolchain was actual setup-ed proper for multilib-scenario. Otherwise you will run into troubles as no runtime for one target might be present. Hope this solves your confusion a bit.
