It sounds like a bug in command-not-found (the package which provides the "currently not installed" suggestion), or out-of-date indices.
Could you try running sudo apt-file update then remove g++-mingw-w64 again sudo apt-get remove g++-mingw-w64 and see what error message i686-w64-mingw32-g++ gives? (Obviously you can install g++-mingw-w64 again after this!)
