Umm...so you've been explicitly #defining stuff as *_imp__stuff all this 
time?  That's NOT the right way to do it.  You should be using 
declspec(dllimport) stuff instead -- which will do the right thing, 
automatically.  See dllhelpers-0.2.6 here:
   http://www.neuro.gatech.edu/users/cwilson/cygutils/V1.1/dll-stuff/

(BTW, the very latest binutils allows you to dispense with all that 
_imp__stuff completely -- but it only works with gcc/binutils.  See 
dllhelpers-0.2.9 for more info.
