Putting #includes before stdafx is a good way to inform a user (of a
source file) about what he needs to add to stdafx.h. Those #includes are
indeed ignored by compiler, but they're useful info for a user. Of
course a user should be familiar with the pch mechanism, since it won't
compile if some #include is missing in stdafx.h.

If a user does not use pch then she would just create dummy stdafx. Simple.
