MingW64 is relatively high on my list of when I get time I will work on that. I started to 
experiment with it once about a year ago, but ran out of time.

IMO it has the advantage that you can work with prebuilt packages, they use the pacman 
package manager and many of gnucash' dependencies are already available prebuilt. A 
notable exception then was goffice, which influenced my decision to choose the csv importer 
as first module to convert to c++. It's the only module in gnucash that depends on goffice and I 
can easily remove this dependency in the c++ rewrite.

So... when I get to finish the importer c++ port, I'll probably focus on Mingw64 again :)
