That error usually means your MinGW version is different.
Have you changed versions recently?
A rebuild of wxMax is usually enough to fix it. Also remember that if you have Quick Build on you'll need to disable it so that the app binaries are recompiled too (otherwise they will refer to old links etc that may no longer exist).
