  New Revision: 52806

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=52806

  Log:
    * missing/explicit_bzero.c: new file. define explicit_bzero.
    * common.mk: add a rule for explicit.o.
    * configure.in: detect explicit_bzero and memset_s.
    * include/ruby/missing.h: add explicit_bzero.
    * random.c (init_randomseed): use explicit_bzero() instead of
      memset(). memset could be eliminated by compiler optimization.
