This article describes how to remove a warning locally in Visual Studio:
http://msdn.microsoft.com/en-us/library/2c8f766e(v=vs.110).aspx
Essentially, the following pattern can be used (guarded by appropriate macros
checking that the code is compiled by the Visual Studio):
#pragma warning( push )
#pragma warning( disable : 4505 )
// The code of the function
#pragma warning( pop )
Regards,
Victor.
