I guess we should set this correctly in libcpp/init.c or wherever. Do 
you see a problem with changing it from its current value of 201300?  We 
don't use the actual number AFAICT.  I guess we could also use a fake 
date for c++1z/c++17.  Say 201500?

They are *off* by default with gnu++NN and *on* by default with c++NN.  
We want them *off* by default for all (gnu|c)++(1z|17).  But -trigraphs 
will restore them for all versions.
