I've found my error, and learned a bit more about all of this :)

my overflow() implementation was incorrect. it needed the following
signature:

  virtual int_type overflow( int_type arg ){}

however, my usage of EOF w/in caused many warnings, but a 
static_cast<int_type>EOF quietened the compiler. 

Q: is using static_cast<> as mentioned above sane? or is there
a more appropriate EOF to use?

Thanks
