i applyed a sligthly larger patch that addresses all the mingw 'ld -r' errors 
that i know of.

apparently i just added few constructors and destructors that were reference 
somwhere in the object files, but were never defined explicitely.
HOWEVER, sometime i needed to add only the contructor, sometime i needed to 
add both and sometime i had to declare the destuctor virtual and some more 
time not... and i have no idea _why_ (i'm no c++ guru).

from my (poor) understanding of c++ class implementation on mingw/cygwin the 
general policy should be: always declare and define constructors and 
destructors.

cheers,
alessandro
