  New Revision: 62408

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=62408

  Log:
    configure.ac: Use `pthread_create` to determine if pthread is available
    
    Instead of `pthread_kill`.  This is because emscripten supports
    `pthread_create` but not `pthread_kill`.

    trunk/configure.ac
