The scanner try to find an stdafx.h in the include paths even though it is considered to be a precompiled header. This makes wrong dependencies.

Example: I setup the PCHSTOP to stdafx.h, and the needed file innerdir/stdafx.cpp (so not in the include paths, but the correct stdafx.h file is there also). If there is a stdafx.h somewhere in the include path, the scons will consider it as dependency (too, the pch dependency also alive).

Full example:

env.Append(CPPPATH = ['FCollada\\FCollada'])
env['PCH']=env.PCH('innerdir\\stdafx.cpp')[0]
env['PCHSTOP']='stdafx.h'
env.StaticObject('otherdir/test.cpp')

Files:

FCollada/FCollada/stdafx.h
innerdir/stdafx.cpp
innerdir/stdafx.h
otherdir/test.cpp

otherdir/test.cpp will be dependent to FCollada/FCollada/stdafx.h, if it is precompiled (begins with #include "stdafx.h")

Bug party triage. Brandon to link up with Steven and document how to do this.
