the latest win32 binary

Hi,
I've searched on google, found insight-mingw-6.6 package which is for
Windows platform, I tried it but seems not accurate, some place are
not able to set breakpoints when they should be, it always breaks at
odd places rather than the main() function,  seems the source file and
line number doesn't match.
I'm using the latest mingw g++ compiler, is there any win32 version of
Insight compatible with it?

Thanks.
