No. The Windows headers that are shipped with MinGW aren't standards-
compliant. You need to compile with -std=gnu++11.

Qt automatically switches to that mode in the modules that require it.

Not with Qt. Qt has the very same ABI, whether you compile it with C++11 or 
C++98.

I know someone has, since there have been fixes for MinGW and C++11 mode coming 
in.

I've been using C++11 and C++0x before that for a couple of years on Linux. 
Since GCC 4.4.
