Mingw is so incredibly slow on windows, I found the toolchain environ really nice when I discovered it. I even managed to get qt+mingw cross compiling, but qt isn't built well for cross-compiling - required so many hard code hacks to make it build properly I don't think I ever want to try sustaining that. I'd be interested to see how hard it is to cross-compile wxwidgets with mingw. At the very least, if we can get the ros libs and headers packaged up with the toolchain, windows development can just unpack these and build with qt or similar, within windows.
Lots of questions, not many answers yet!
The willow garage guys have just opened up a new project on their code server - eros. It's goal is to assist with both cross compiling and anything related to using ros on embedded systems. The mingw toolchain is something I've wanted to look at as well, so if we can collate information there from various people doing testing, that'd be good - please sign up and let's use the mailing list/forums to jot notes if you're interested.
p.s. Not much there yet sorry, only been two weeks and currently a bit bombed at work with projects closing and holidays approaching. Will have some good time for it when I take some leave, but should have ported some python scripts and patches to make cross-compiling easier (from our Yujin Robot packages) within a week or two.
Regards,
Daniel Stonier.

Dear Daniel,
I never thought about the idea to cross compile for windows using mingw
on my linux box. I asked google and that seems to be quite common.
These mingw libs can be used together with MS Visual Studio
(source http://www.mingw.org/wiki/MSVC_and_MinGW_DLLs)
gcc -shared -o testdll.dll testdll.c
-Wl,--output-def,testdll.def,--out-implib,libtestdll.a
lib /machine:i386 /def:testdll.def
cl testmain.c testdll.lib
by using visual studios lib program to generate a VS compatible lib file
from the gcc-generated def file.
As mingw uses the Win-API without intermediate layer like cygwin does
there should be full Win7 (both 32 and 64bit) compatibility. I did not
test this yet, but I am quite optimistic.
