Re: [ns] undefined reference to `__eh_pc' and Re: C++ Compilation problem

Often these kinds of strange link errors (missing symbols that don't
appear in the code *anywhere*) are due to compiling with g++ and
linking with something else.  Apparently g++ fills in lots of the C++
magic (templates, virtual function tables, exception handling code) at
link time.
