Unsupported 16bit resouce in type library?

I have a type library created with the Delphi Type Library Editor, which
is now causing RLINK32 to {*word*88} with an "Unsupported 16bit resource"
error.

Has anyone ever seen this before?

What possible resource could there be in the TLB which is causing this,
and how do I fix it (I don't really want to have to re-create the entire
TLB from scratch, and I *definitely* don't want to have to fall back on
IDL and MIDL).

PLEASE reply by *email*.  Thanx in advance,

Regards,

Jolyon Smith
