* malloc/obstack.c: Fix old comments. Update FSF snail mail address.
* malloc/obstack.h: Likewise.
[BZ #321]
Fix portability bugs encountered when porting to Itanium.
* malloc/obstack.h (obstack_empty_p, obstack_finish): Do not
assume that the "contents" member is suitably aligned. It is
not, for some hosts and alignments: e.g., Itanium, long-double.
* malloc/obstack.c (_obstack_begin, _obstack_begin_1,
_obstack_newchunk): Likewise.
* malloc/obstack.c: Include <stddef.h>, for size_t.
Include <inttypes.h>, <stdint.h> if needed and available.
(DEFAULT_ALIGNMENT): Now an enum constant, not a macro.
Use C89 offsetof rather than K&R trick.
Use the maximum alignment of uintmax_t, long double, void *
rather than the alignment of double.
(union fooround): Use uintmax_t, long double, void * members
rather than just long and double.
[BZ #321]
Fix portability bugs encountered when porting to the IBM iSeries,
where pointers are 256 bits wide and no integers are that wide.
* malloc/obstack.h (__PTR_TO_INT, __INT_TO_PTR): Remove.
All uses changed to:
(__BPTR_ALIGN, __PTR_ALIGN): New macros.
(struct _obstack_chunk.temp): Change from int to a union
of pointer and int. All uses changed.
[BZ #321]
* malloc/obstack.c (print_and_abort) [!_LIBC]:
Call fprintf (stderr, ...), not __fxprintf (NULL, ...).
[_LIBC && USE_IN_LIBIO]: Don't include <wchar.h>; no longer needed.
