+       Port --enable-checking=all to Fedora 14 x86.
+       * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
+       Move to lisp.h.
+       (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
+       (overrun_check_realloc, overrun_check_free):
+       Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
+       That way, xmalloc returns a properly-aligned pointer even if
+       XMALLOC_OVERRUN_CHECK is defined.  The old debugging code happened
+       to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
+       * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
+       into account when calculating the initial malloc maximum.
+       * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
+       Move here from alloc.c, so that charset.c can use it too.
+       Properly align; the old code wasn't right for common 32-bit hosts
+       when configured with --enable-checking=all.
+       (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
+       (XMALLOC_OVERRUN_SIZE_SIZE): New macros.

        * sysdep.c (snprintf) [EOVERFLOW]: If EOVERFLOW is not defined,
