以上可编译成功，但使用上编译老代码会出现问题。

新方案，使用系统自带mingw-w64，再升级header、crt部分。

$ sudo apt-get install mingw-w64

$ ../mingw-w64-headers/configure --host=x86_64-w64-mingw32 --prefix=/usr/x86_64-w64-mingw32
$ make
$ sudo make install

$ ../mingw-w64-crt/configure --host=x86_64-w64-mingw32 --prefix=/usr/x86_64-w64-mingw32/ --disable-multilib
$ make
$ sudo make install
