[Qt-interest] Cross-compiling Qt (linux -> windows)

[Victor Leschuk]

I have a win7 build box on a virtualbox, however it is not an option, it is
necessary to get automated build procedure hosted on Linux environment.
Currently I am trying similar way that described here
http://lists.qt.nokia.com/pipermail/qt-interest/2011-March/031912.html - the
guy was compiling windows binaries from mac os. I studied and adopted his
configuration scripts to my cross-compiler and now giving it a try...
