Thanks; my idea is that since we don't want to make widl load a tlb
from a builtin dll, we'll need to ship the raw tlb, and it would make
sense to ship it in the include dir since the lib dir already contains
the builtin dll. And when building Wine itself, we'll need the raw tlb
in order to build the includes, since we can't build the builtins
before the includes, so in both cases we'll want to load the tlb from
the include dir. Does that make sense?
