That (symlink), nor copying to "dllwrap", didn't help.

I'm afraid the issue is that when cross-compiling, dllwrap cannot be invoked
as it is a win32 program.
In the various mingw32 ML posts I read the suggestion to replace calls to
dllwrap by "gcc -shared ...." calls. Unfortunately that is beyond my
expertise.
