allow to build for Windows XP when using Visual Studio 2012

VS 2012 Update 1 added the possibility to target Windows XP by using a
SDK that is based on the Windows 7 one.
http://blogs.msdn.com/b/vcblog/archive/2012/10/08/10357555.aspx

This patch probably should not be integrated as is, as it disables a
test that fails in this configuration (CppunitTest_connectivity_ado)
