//
// It also filters out any contribution from files named *.h or *.c, based
// on preprocessor line markers. When preprocessing RC files, the included
// headers can leave behind C declarations, that RC doesn't understand.
// Rc.exe simply discards anything that comes from files named *.h or *.h.
