Can you post the errors? I have no access to any Windows systems, but
from the errors I might be able to work out what is going on. Better
still if you can post a fix. :-) [Or send it to me direct.]

Making the building of Unicode support the default does not alter the
runtime defaults, which have not changed, and are non-Unicode.

Oh dear. That suggests it is tied up with the Windows way of handling
libraries, about which I know nothing. If you cannot help, perhaps
eventually another Windows user on this list will be able to sort this
out. I hope so.
