dnl blow us up if we ever include hash_map -- yet it's present and I
dnl can't make the autoconf test fail.  The replacement is
dnl unordered_map, which is not just a nonstandard header: it also
dnl requires language extensions in order to work.  So, since aptitude
dnl has no real need for hashes anyway, I'm just removing all the
