    Port --enable-checking=all to Fedora 14 x86. · cb993c58
    Paul Eggert authored
    * 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.
