  Looks good.  Could you also do "chmod -x *.c" in the CVS directory?
Having executable C files is... odd.  Many of the text files appear to
be executable, too...

  Some should probably ssize_t, too.  e.g. the return code from recvfrom().

  I'd suggest also changing UINT4 to uint32_t, etc.  It's 2007, C has
moved on from where it was in 1996. :)

  I'd check hp->h_addrtype && hp->h_length in the code, to be sure it's
an IPv4 address.  Maybe also memcpy() hp->h_addr into a temporary
variable?  Though h_addr should be aligned...

  Sounds good to me.

  It's getting close to the point where we'll need to release the
dictionaries as a separate package, I think.
