Interlocked functions - cannot convert arguments

I need to compile cppunit on ARM platform. All compiles and works fine on release mode, but on debug mode I get following errors: 

Error   1   error C2664: 'unsigned int CppUnit::_InterlockedIncrement(volatile unsigned int *)' : cannot convert argument 1 from 'volatile long *' to 'volatile unsigned int *' C:\Program Files (x86)\Windows Phone Kits\8.1\Include\winbase.h 8959    1   cppunit

I am struggling with it for days now, and I cannot really find any solution to this. I am using visual studio 2013.

Just a hint: mingw users may define NOWINBASEINTERLOCK to omit Interlocked* functions in Windows.h and use something like std::atomic instead.

Ran in to the same thing - seems like you're including from inside a namespace (CppUnit in your case). The compiler doesn't like that - make sure your #include is outside of all namespaces.
