[Qt-interest] build of qt 4.4.3 with mingw fails on Windows 7 due to conflicting InterlockedCompareExchange

[mail at philippmuenzel.de]

Hi folks,

I'm setting up a new Win7/64 rig for development. For backporting purposes, I need a Qt v 4.4.3 installation.

I tried both Ming with gcc 4.4.1 that is shipped with CodeBlocks and mingw with gcc 3.4.5 that can be downloaded with the mingw installer from sourceforge. Both tries, I configured with

configure.exe -release -shared -no-sql-sqlite -no-qt3support -no-vcproj -no-phonon -no-phonon-backend -no-webkit -platform win32-g++

with success, but running ming32-make fails with

I clearly remember that I once built a Qt from the sources with mingw, but that was on WinXP/32.

So what is the problem here? Win7? 64bit? improper Qt sourcecode package? Faulty mingw installation?
