Ok, a couple of things:

In make_import_fixup in ld/emultempl/pe.em, it uses rel->addend
without also checking for the inline offset.  For formats that use an
inline addend, rel->addend may be zero.

Addends are very tricky in PE.  There's lots of comments about adding,
subtracting, adding, subtracting, etc, in various places in the code.

I don't think an import library *can* specify an offset to be added at
runtime.  From my understanding of the dll import/export system,
windows simply places the address of the thing being imported in the
location indicated.
