The plugins have not been tested with mingw yet.

I tried it, with mingw on debian as a cross compiler and 
confirmed the compile errors you have.

The problem is a name conflict between the Spice headers and the 
mingw headers.  To fix that (and another you didn't get to yet) 
Change wrapper.cc ..
======From======
// spice includes
extern "C" {
  #define NODE NodE
  #define public PubliC
  #define bool BooL
  #define main MaiN
  #include "capabil.h"
  #include "const.h"
  #include "iferrmsg.h"
  #include "devdefs.h"
  #include "ftedefs.h"
  #undef main
  #undef bool
  #undef public
  #undef NODE
  #undef OPT
  #undef LINEAR
}
======To=======
// spice includes
extern "C" {
  #define _complex CompleX
  #define NODE NodE
  #define public PubliC
  #define bool BooL
  #define main MaiN
  #include "capabil.h"
  #include "const.h"
  #include "iferrmsg.h"

}
============
.. notice the added lines.

But then there is still a problem .. Link fails with a big list 
of "undefined reference".  I don't know what to do about it.  
They get resolved later when the plugin is used, so they should 
not be required at the link step.

I don't have a windows system, so I need help on this one.
Can anyone help here?
