I think this is what the ld manual is hinting at at the end of the
section "direct linking to a dll":
<http://sourceware.org/binutils/docs-2.16/ld/WIN32.html>

"Sometimes it is necessary to include pure static objects within the
import library (which otherwise contains only bfd's for indirection
symbols that point to the exports of a dll). Again, the import lib for
the cygwin kernel makes use of this ability, and it is not possible to
do this without an import lib."

On an unrelated note, I had always thought that direct linking to a dll
took *more* resources during link compared to using an import library,
but apparently this is backwards.  I guess it pays to RTFM.
