All "generated" source was manually modified (with the power of search/replace), but I believe the "source input" files have been adjusted (checked into revs 53098 and 53099) to reflect the necessary changes (with possible whitespace formatting differences). The Microsoft compiler doesn't flag "unused function parameters", so I apologize in advance if I may have missed a few. The "dcerpc_info* di" parameter is used in almost every function. svn path=/trunk/; revision=53100
