> 1>D:\Users\crolke\git\qpid-cpp\src\qpid\log\Logger.cpp(48): error C2440: 'initializing' : cannot convert from 'int' to 'qpid::sys::PODMutex'
> 1> No constructor could take the source type, or constructor overload resolution was ambiguous
> {noformat}
> The issue is with the definition of QPID_MUTEX_INITIALIZER.
> In Linux it is defined as PTHREAD_MUTEX_INITIALIZER which is a complex structure initializer.
> In Windows it is a naked 0.
> In a stand-alone windows program
> {noformat}
> std::is_pod<PODMutex>::value
> {noformat}
> returns false. In Linux the same statement in qpidd broker returns true.
