Actually, I was talking about IMAGE_SCN_TYPE_DISCARDABLE and IMAGE_SCN_TYPE_REMOVE. See: http://sources.redhat.com/ml/binutils-cvs/2005-06/msg00084.html and http://sources.redhat.com/ml/binutils-cvs/2005-06/msg00087.html for the binutils changes. FWIW, MSVC's dumpbin program now says this about the sections: . . .
