stdafx.h looks like this (it's the "..\otherproject\superfile.h", and
similar lines immediately following, that are my concern):
* neither stdafx.h nor superfile.h start with //{{NO_DEPENDENCIES}}
* I do a complete rebuild, and the problem doesn't go away (so it's not obj
files being dated in the future)

// stdafx.h : include file for standard system include files,

// or project specific include files that are used frequently, but

// are changed infrequently
