IUnknown and any class derived from it have inconsistent codeview debug info:

dmd -g -c lib

module lib;
interface IUnknown
{
    void foo();
}

compiles to

$$TYPES    segment
00: LF_ARGLIST   argcount=0 
01: LF_VTSHAPE   count=1 05 
02: LF_CLASS     count=1 <typidx 1007> property=x0000 <dList 0000> <vshape
1001> length=x0000 lib.IUnknown 
03: LF_CLASS     count=0 <typidx 0000> property=x0080 <dList 0000> <vshape
0000> length=x0000 IUnknown 
04: LF_POINTER   <x000a > <typidx 1003> 
...

and later referencing the incomplete type 1003. Please note that the class is
called "lib.IUnknown" in one entry, but "IUnknown" in the other.
