First, when you specify `--host`, you should specify `--build`; otherwise `configure` may get 
confused if test programs can be executed successfully, for example, when wine-binfmt has installed.

Second, you should call `make` instead of `mingw32-make`. The latter is for use 
in CMD only.

And, this works for me:

   ```
   ./configure --build=x86_64-pc-linux-gnu  \
               --host=x86_64-w64-mingw32  \
               --enable-term-driver
   make -j4
   ```

There is probably more stuff that should be disabled for mingw-w64. You should 
have read README.MinGW.

That's because the x86 ABI of Windows has a convention to prefix function names with underscores. 
You can just ignore the inconsistency. (It's a bit more complex, but I will keep the answer simple 
here.)

However, it looks like that buffer overflow checking is enabled by default in the compiler that you 
use. This can be disabled by undefining `_FORTIFY_SOURCE`:

   ```
   ./configure --build=x86_64-pc-linux-gnu  \
               --host=x86_64-w64-mingw32  \
               --enable-term-driver  \
               CPPFLAGS='-U_FORTIFY_SOURCE'
   make -j4
   ```
