That seems like it's worth a distinct bug report that can focus > just on that. I don't think that is a bug though because that mingw toolchain was configu= red with --enable-threads=3Dsingle in that case (so libstdc++ does not have the= full support). Most likely it needs to be configured with --enable-threads=3Dwin= 32 to support that.=
