OK, i might have been too hasty.
libtool does have some code to allow .def files to be used. However,
it doesn't really work as expected, see the output of `make' (attached).

The reason is, i believe, that EXPORTS is not on the first line. If
it's moved to the first line (above the comments), then libtool groks
it correctly.

libtool version:
macro_version=2.4.2
macro_revision=1.3337
