I don't think they're special to the front end either, it transforms "new T"
into a call to the relevant library allocation function and then invokes a
constructor. The allocation functions are just ordinary functions implemented
in libsupc++ but as weak symbols so they can be overridden. If we just declare
them externally_visible in libsupc++'s <new> won't that work?
