Conditionally include the PCH's, then define something like "#define _PRE_COMPILE_" This way the original headers are still visible and the code is modular if you so need. An example of this would be to include

#ifdef _PRE_COMPILE_
#include "stdafx.h"
#elif
#include 
#include 
#endif

Include this at the beginning of every source file.
