G++ always wants to dynamically link to libstdc++. (There is no dynamic 
version of libsupc++; it's integrated.) You have to pass -static in 
order to link against the static runtimes.
And at least in x86-64, it's impossible to link a shared object against 
the static runtimes, because they're not compiled with -fPIC. I have 
tried and found it impossible to somehow get a .so and a main executable 
with mismatching runtime linkage work together.

So I think we're pretty safe on this front.

(By the way, I've finished the implementation using my newest model, but 
it's late. I'll compile it and the write about it tomorrow.)
