Or maybe we need to recommend use of -fpermissive?  If C++ thinks
casting void * to something else is illegitimate, it's basically not
going to cope with most things we might try to inline in Postgres.
And I don't think that saying "you don't get to call these fundamental
support functions from C++" is likely to fly, so just hiding the
functions won't help much.
