  New Revision: 64160

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=64160

  Log:
    mjit.c: suppress warnings by -Wunused-value
    
    on MinGW with __atomic_exchange_n(). It returns the previous pointer value but
    obviously it's not needed in MJIT's usage.
    
    mjit.c: In function 'compact_all_jit_code':
    ruby_atomic.h:11:36: warning: value computed is not used [-Wunused-value]
     # define ATOMIC_EXCHANGE(var, val) __atomic_exchange_n(&(var), (val), __ATOMIC_SEQ_CST)
                                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  Modified files:
