Define to ptrdiff_t, without bothering to check HAVE_STDDEF_H.
(This type really should be intptr_t, but that's a C99ism.)
(_obstack_memcpy): Remove: all uses changed to memcpy.
Include <string.h> unconditionally.
(struct obstack): Assume __STDC__ for types of members
chunkfun, freefun, extra_arg.
(_obstack_newchunk, _obstack_free, _obstack_begin, _obstack_begin_1,
_obstack_memory_used, obstack_alloc_failed_handler, obstack_init,
obstack_begin, obstack_specify_allocation,
obstack_specify_allocation_with_arg, obstack_chunkfun,
obstack_freefun, obstack_free) [! (defined __STDC__ && __STDC__)]:
Remove unprototyped decls and the macros that use them.
(__INT_TO_PTR) [__STDC__]: Cast result to
(void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
when compiling Bison 1.875's `bitset bset = obstack_alloc
(bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
(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.
