  New Revision: 37742

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=37742

  Log:
    * configure.in (--enable-dtrace): always call RUBY_DTRACE_BSD_BROKEN
      for portability.
      As the note, FreeBSD 8 has DTrace as the optional
      feature (it is enabled by the build option), but doesn't have USDT.
      FreeBSD 9 has USDT but they are still optional. FreeBSD 10 will
      enable them by default.
      The variable $rb_cv_prog_dtrace_g is "yes" only on FreeBSD 9 with
      optional DTrace or FreeBSD 10. If it is "no", you cannnot know
      whether it doesn't need -G or DTrace is disabled. (by cheking
      error code, you can know)
    
    * configure.in (--enable-dtrace): change help message
