  New Revision: 65151

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=65151

  Log:
    .travis.yml: add -pedantic build
    
    Now that we have allow_failures, why not add configurations
    that are prone to fail.  The first thing I want to add is
    $CC -ansi -pedantic, which spots lots of bugs on my local
    machine.
