On my system, running the command

  $(LN_S) .libs/foo.dll DLD-FUNCTIONS/foo.oct

in the parent of the DLD-FUNCTIONS directory creates a symbolic link
in the DLD-FUNCTIONS directory with the name __convn__.oct that points
to the file .libs/foo.dll.

Ah, but Windows doesn't have symbolic links and $(LN_S) is just cp, so
I guess this fails.  OK, I think what we need to do is

  cd DLD-FUNCTIONS && $(LN_S) .libs/foo.dll foo.oct

so that it will work correctly with either cp or "ln -s".  I've made a
change that should do this correctly now.  The updated versinon of my
patch is now on http://jweaton.org/automake-diffs.gz. This version of
the patch includes all the other changes I made on Friday.

Thanks,
