I have several in mind.  :-)

Either way suits me fine; the user will have to either add an
option (-D_GLIBCPP_DEPRECATED) to get the function, or add an option
(-Wno-weird-phil-hooks) to /not/ be warned about it.  Either way the user
must take action, which is good.  And since only one of these possibilities
actually exists right now, let's use that one.  :-)

I'll add DEPRECATED and supporting documentation this week.
