I don't see this as an immediate issue but...

a new patch is attached.

Well it won't change anything for Moonlight[1] but it will still bite
any other (well future) user of coreclr unless the BCL they provide
offers the required COM types [2]. Otherwise it will simply abort (like
id does today).


[1] unless someone adds a [ComImport] somewhere in the platform code -
but that would not pass our test suite :)

[2] A added a FIXME in the patch about this. In any case the g_abort
should make it clear enough to runtime embedders
