[Insight-users] cross compiling ITK with mingw32

[Tom Vercauteren]

Great. Thanks for the update. I guess the next step would be to
automate that. This will require getting rid of the tryrun in the
CMakeLists and could rely on wine to run the unit tests from the
source machine.

I have added this to the ITK 4.0 wishlist:
