    * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
    (elsz): Now a signed constant, not a size_t var.  We prefer signed
    types to unsigned, to avoid integer comparison confusion.  Without
    this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
    "cannot optimize loop, the loop counter may overflow", a symptom
    of the confusion.
