Has anybody used virtual functions in djgpp.  I have a base class
declared with virtual functions.  I derive a calss from this base class
in which I overide the virtual functions.  When I try to link however,
any reference to these methods in the code file for the derived class
shoot out an error that looks like this:

code.o:code.cc:undefined reference to  "the virtual function as it
appears in the base class declaration"

Can anybody shed some light on this?
