Cross-compiling the Windows emulator on Linux?

The instructions for cross-compiling the emulator for Windows for Linux aren't working for me. In particular, it's failing at link time with a slew of errors about missing functions staring with _Pa, Fl*:: (C++?). I've attached the log file from the make on the off chance it'll help.

Anyone have such builds working? Maybe familiarity enough with such cross-compilation to provide clues as to where to look for this issue?

you'll need to install wine, pulseaudio and the fltk dev packages for your distro, but even after all that I still couldn't get the cross compile to work, it always falls over at linking to the windows library's, yet cross compiling works for other software

Wine? Is that pulled in with the mingw cross compiler? The docs list the pulseaudio and fltk packages (though the ones it lists are way out of date) and the mingw cross compiler.

We seem to be in the same state, though. I suspect there's a missing dependency somewhere for those libraries.
