Well, we're going to have to think of something, because as more of us
move onto the newer gcc releases the annoyance level is going to become
intolerable.

I think a large fraction of the -Waddress warnings are coming from
this line in the heap_getattr macro:
AssertMacro((tup) != NULL), \

Seems to me we could just lose that test and be no worse off, since
the macro is surely gonna dump core anyway on a null pointer.

But some of the remaining -Waddress warnings are not so painless to
get rid of.  Ultimately we might have to add -Wno-address to the
default CFLAGS.
