Build warnings in VS 2013

[Matt Feemster]

Building quantlib 1.4 for x64 in Visual Studio 2013 Update 4 produces a few warnings. The project settings say to treat warnings as errors (/Wx), so this prevents the build from completing.

May I suggest either fixing the warnings, or making the compiler settings less strict (/Wx-)?
