// COM_MINOR_VERSION = 1 (NT4.0, SP1, SP2, DCOM95). // - Initial Release // - Must be used when talking to downlevel machines, including // on Remote Activation calls. // COM_MINOR_VERSION = 2 (NT4.0 SP3 and beyond). // - Added ResolveOxid2 to IObjectExporter to retrieve the // COM version number of the server. Passed to the NDR engine // to fix fatal endian-ness flaw in the way OLEAUTOMATION marshals // BSTRS. Previous way used trailing padding, which is not NDR // compatible. See Bug# 69189. // COM_MINOR_VERSION = 3 (DCOM95 build 1120 and beyond) // - OLEAUT32 added two new types to the SAFEARRAY, but SAFEARRAY // previously included the "default" keyword, which prevented // downevel NDR engines from correctly handling any extensions. // Machines with version >=5.3 don't use "default" and will // gracefully handle future extensions to SAFEARRAY. // COM_MINOR_VERSION = 4 (NT5.0 1779, NT4 SP4, DCOM95 2328, and beyond) // - 1) Fix for incorrect marshal/unmarshal of array of interface // pointers by NDR. Wire representation is corrected. // - 2) Fix wire representation of a conformant struct embedded in a // complex struct. // Both fixes kick in when DCOM version is >= 5.4 or the call // is raw RPC.
