patch to change sprintf to snprintf in inet_ntop.c for SunOS4

[Dave Dykstra]

I found that inet_ntop.c was depending on the return value of sprintf to
return an int, but on SunOS4 it returns a char *.  Snprintf is preferred
anyway, so here's a patch to change the calls to use snprintf.  Applies
cleanly to the current CVS, and it was the only patch I need to apply to
get 2.9p1 to build on SunOS4.1.4.

On the other hand, I can't see any where inet_ntop is called, and the
symbol doesn't appear anywhere in the binaries on SunOS4 or Solaris.  
Can the file just be deleted?
