  New Revision: 45001

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=45001

  Log:
    ruby.h: use FIX2LONG
    
    * include/ruby/ruby.h (RBIGNUM_SIGN): use FIX2LONG() instead of
      FIX2INT() for optimization, since rb_big_cmp() returns only
      Fixnum -1..+1 for Finxum 0.
    
      (RBIGNUM_POSITIVE_P, RBIGNUM_NEGATIVE_P): ditto.
