arithmetic on void pointers

[Russ Rew]

GNU C supports arithmetic on void pointers, but the manual implies
that this is an extension to the C language.  I could find no
prohibition on arithmetic on void pointers in K&R second edition.
What does the latest dpANS document say?  Is it legal to increment a
variable of type void* ?
