  New Revision: 49103

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=49103

  Log:
    * eval.c (ruby_init): Print ruby_setup() error only in debug mode.
      Unsupressable error message is not a good idea.
      Note that the message is printed sometimes with following
      code (highly timing dependent, though):
      pid = spawn("ruby -e ''"); Process.kill(:TERM, pid)
