Subject: Cosmetic fix to xntp 3-5.88 (ANSI compilation)

Hi!

Here is small fix to last version regarding ANSI copilation. My compiler
complaints, that in xntpd/refclock_atom.c the function atom_cmpl_fp () has
prototype int (*)(void *, void *) when it is expecting
          int (*)(const void *, const void *).
as defined in qsort():
extern void qsort(void *, size_t, size_t,int (*)(const void *, const void *))

There seems to be two possibility:

1. check in configure wether qsort needs const
2. just define atom_cmpl_fp () with const.

I opt for the second; AFAIK the standards (POSIX et al) indeed require
const void *; also if function expects void *, const void * should be 
legal as well.

So here is one-line patch. Just to keep fussy compilers happy :-)

thanks for the greate job done!!!

PS. you use patch to automake 1.0. Is it official? I couldn't find it on
any GNU site.
