Support Statement: Duplicate COM symbols in different TypeLibs

In a legacy code, two different COM IDFs defined the same class -- MSCOMCT2.DataObject and MSCOMCTL.DataObject

gmBasic seems to take the first one as the source; in this case MSCOMCT2.

I want to use the MSCOMCTL once since that custom IDF has more customizations and the type was being used in the context of other MSCOMCTL types.

Ultimately, its one of those things where we probably need to either duplicate work or do what I did which was pre-edit a fully qualified name:

 <Replace status="active" name="make sure the tool picks up MSComCtlLib.DataObject instead of MSCOMCt2">
   <OldBlock><![CDATA[ As DataObject]]></OldBlock>
   <NewBlock><![CDATA[ As MSComCtlLib.DataObject]]></NewBlock>
</Replace>

Another option is to create a merged custom IDF for all the different versions of Windows Common Controls (This is something we routinely do for ADODB); however, that won't work in general, as you can see in the example below:
