Why subtract value like that?  The 0 cast was necessary and sufficent
for portability to K&R.  NULL is only correct if the compiler is ANSI
and the prototype for gettimeofday is in scope.  style.9 specifies
casting NULL when it is used in function args.  inetd.c was sort of
portabile to K&R.  Portability to both K&R and ANSI was broken by
subtacting value in rev.1.17 - gcc's typeof feature doesn't work in
traditional mode for some reason, and of course it doesn't work in
ANSI C.
