64bit dnscache

[Jeremy Kister <djb-dns@jeremykister.com>]

I have a need to run dnscache with more than 4GB memory.

I've got a Solaris 9 machine on a Sun Fire V215 dual cpu with 10GB RAM.

I appended "-m64" to both conf-cc and conf-ld, changed cache.c's
cachesize max to 33285996544 and compiled -- everything seemed to
compile fine.

But I get an error whenever at (or above):

# grep . DATALIMIT CACHESIZE
DATALIMIT:4294967296
CACHESIZE:4000000000

dnscache: fatal: not enough memory for cache of size 4000000000

I thought it might automagically work, but I was apparently wrong.

Google's got some info about a patch for tinydns running 64bit, but i 
didnt see anything for dnscache.
Does anyone have tips to run dnscache with more than 4GB ram and/or 
compiled 64bit?
