As I understand it [and note: I have *not* tried it] the documentation
there is wrong for MinGW. You should pass a *.def file as the
parameter when the compiler target [ie. "host"] is Windows.
The libtool code suggests that in addition a .def file is accepted by
libtool on Windows hosts, but this is undocumented and the detection is
very simplistic:
# exporting using user supplied symfile
if test "x`$SED 1q $export_symbols`" != xEXPORTS; then
# and it's NOT already a .def file.
So passing LIBRARY as the first line doesn't work. :-(
However, passing a simple one-symbol-per-line file should work.
