The only problem with inet_addr() is if it encounters an error.  It
returns -1 on error, which, unfortunately, is a valid IP address
(  This would generally be considered a problem.
inet_addr() is a part of BSD 4.3, and I know at least Linux adopted
it, but I don't know about any other operating systems; and I'm
fairly certain Winsock doesn't support it.

The inet_aton() function fixes the -1 error (it returns the binary
address in an in_addr structure); but the portability issue remains.
It'd probably be best to do as Jeremy did, and convert to binary data
(perhaps move it to a function as you suggested).

->Sounds like it would be useful to some people and not break anything else.

I can't imagine it being all that useful, but since it's rather
insignifigant, I don't see why it shouldn't be added.  The trouble is
in deciding how to implement it.  Just a config.c variable that
contains the IP in dot-notation form?

   * set to NULL to use INADDR_ANY (bind to all IP addresses this
   * server has), or set to the specific IP of this server that you
   * want to bind to in dot-notation form (e.g., "")
  char *bind_to = "";
