Yep.  Known problem with Wine.

Good question.   It's probably pretty involved; you may have to wait
for an expert to try it and see what it breaks.  Alexandre suggested
it might not work recently (see
http://bugs.winehq.org/show_bug.cgi?id=10273#c17 ), but
perhaps he's being overly pessimistic.

BTW if that idea works for Solaris, it might work for Linux, too.

It works on Linux already, we are using prelink to set the kernel32 load
address. That doesn't mean you can avoid -fPIC since the address is not
guaranteed to be available.
