r3611: DCOM client support works!!
The torture test DCOM-SIMPLE now successfully does an IStream_Read and a IStream_Write call. This test can now be run successfully against the "Simple DCOM" Visual Studio example. (You have to quote out line 337 in pidl. pidl complains if the variable that contains the array size follows the array. I still need to fix this properly) Next goals: - Clean up code - Server side support - Support custom marshalling - Support DCOM interfaces in files other then dcom.idl (This used to be commit 8693344772a9b700533179f4bacfe27ec27dfcfe)
