  New Revision: 66029

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=66029

  Log:
    .travis.yml: avoid bashism
    
    GCC_FLAGS is not an array and CC is finally passed to configure as
    single string.  Pass CC via the environment variable, so it does
    not need to be quoted anymore.

    trunk/.travis.yml
