# HG changeset patch
# User Jim Meyering <jim@meyering.net>
# Date 974541009 0
# Node ID 30966a6478bc1a73bdae99576c3ee2d19fd53977
# Parent  a8b23ca249d7a80922bdd4483318ce89a2b37c2c
Formatting changes.
(obstack_grow, obstack_grow0): Don't cast WHERE at all: that would
prevent type checking.
(obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
cast the value to (void *): assigning a `foo *' to a `void *'
variable is valid.
(obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
