windows build warnings

hello

when building pg_admin with profile "Release->Win32" from trunk I get those warnings:
Warning    1    warning C4627: '#include "wx/generic/gridsel.h"': skipped when looking for precompiled header use

using :
Microsoft Visual Studio 2008 9.0.21022.8 RTM with Microsoft Visual C++ 2008   91605-031-5000002-60990
wxMSW-2.8.10

the built exe does not crash, but I feel kind of insecure.
