Ideally, I would like to get a warning if it is called from code that 
was compiled "-pedantic".   If that's too hard, it would suffice for
it to be an error in that case.

I recommend adding a comment in its place that suggests replacing uses 
of "v.push_back()" with "v.resize(v.size()+1)".  This might be added
to the docs as well.
