The new mingw-builds package is indeed an improvement. So I think we should really switch to

http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/4.8.2/threads-posix/dwarf/i686-4.8.2-release-posix-dwarf-rt_v3-rev3.7z/download


for the 5.3.0 & 4.8.6 release packages, CI system etc.

I created

https://bugreports.qt-project.org/browse/QTBUG-37406 (5.3.0 binary installer)
https://bugreports.qt-project.org/browse/QTBUG-37407 (4.8.6 binary installer)
https://bugreports.qt-project.org/browse/QTQAINFRA-835 (CI system)

to track this.
