Debian has Windows cross-compilers. You can even build Windows installers without leaving Linux, using NSIS. You could even test under Wine, that probably doesn't cut it though.
That's crazy talk. Nobody (except some outsider outliers) developers on Debian to deploy on Windows, no matter what experimental, half-working cross-compilters it has...
The mingw cross-compilers have been around for like a decade, are far from experimental and work great. Many open source projects use them to produce executables for Windows users.
