Building libstdc++.dll may be a "hard problem" for a mathematician or for libtool, but this is how an ordinary person coud do it.
dlltool --output-def libstdc++.def --export-all libstdc++.a gcc -shared -olibstdc++.dll -Wl,--out-implib,libstdc++.dll.a \ libstdc++.def libstdc++.a The main problem after that is in getting rid of the need for auto-import of data objects by marking header files appropiately.
