[Insight-users] cross compiling ITK with mingw32

[Tom Vercauteren]

Hi Mario,

I never tried to compile the entire ITK with mingw from linux. However
from my small linux mingw experience, I saw that mingw is case
sensitive on linux but not on windows. Did you try replacing
  Float.h
by
  float.h
?

Hope this helps,
Tom

P.S.: Let me know if you manage to cross-compile all of it. This is
something I wanted to try at some point.
