--- Comment #9 from ralphengels at gmail dot com <ralphengels at gmail dot com> 2011-04-20 15:17:40 UTC --- if its any help i noticed that cpp.exe seems to have a dependency on libstdc++6.dll "somewhere" since dependency walker says it doesnt but it barfs pretty loudly if its not there. strange thing is the libstdc++6.dll it wants is the gcc-4.6.0 one (which isnt even built yet) so i had to copy an earlier build to path for it to pick it up. ill try a static build to see if it still throws the error.
