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

[Philipp Münzel]

I now tried several versions of mingw. It seems that only gcc 3.4.2 is 
supported with qt < 4.5 and only gcc 4.4.1 with the later versions. 
Intermediate versions like gcc 3.4.5 produce the error.
At least I have found an old mingw installation with gcc 3.4.2 that 
compiles qt 4.4.3.
I think, I'll have to put this mingw version on a separate disk and 
store it in a bank vault ;) in case I ever need it again.
