Hmm.  I have a makefile that just installs things on windows from linux.
It moves the DLL out of the way if there are running apps.

Then I switch to my windows box using either vnc or my Cybex SwitchView.
If necessary, I close all apps and restart them so that they are running
the new DLL.

I don't see a way around this no matter where you are going to be
installing the DLL.

Corinna once ported an internal application, called libremote, which
might allow you to do something like this.  I don't know if it allowed
a linux gdb to debug a Windows app, though.

Corinna?

Does Wine even run Cygwin?  The last I remember someone was asking us
to make Cygwin changes to accomodate Wine.
