This is the configure line I use to build it:

./configure --with-pic --build=`./config.guess` --host=i586-mingw32msvc \
        --prefix=/usr/i586-mingw32msvc

But I must admit that that's with a somewhat old version of mingw.
Things might have changed.  (It's also on a 32-bit system.)

The suspicious thing here is that I'm pretty sure there shouldn't *be*
any undefined symbols.  Can you see what "U" lines nm outputs?

Thanks,
