VPATH is also broken [1] in some mingw-w64 builds (eg. rubenvb).

I have made positive experiences with mingw-builds [1], which usually 
work quite well.


But be aware that building Qt using GCC C++11 (-std=c++11) can be quite 
tedious (at least it was), especially when it comes to JSC (namespace 
problems, non-standard syntax).

You can theoretically create C++11 applications using C++98 Qt 
libraries. The problem is that GCC C++11 is not fully binary compatible 
with GCC C++98. But I'm quite sure Thiago can clarify on how this 
affects Qt binary compatibility.
