      compat/atomics: add typecasts in atomic_compare_exchange_strong() · 6a93b596
      Wan-Teh Chang authored
      The Solaris and Windows emulations of atomic_compare_exchange_strong()
      need typecasts to avoid compiler warnings, because the functions they
      call expect a void* pointer but an intptr_t integer is passed.
      
      Note that the emulations of atomic_compare_exchange_strong() (except
      the gcc version) only work for atomic_intptr_t because of the type of
      the second argument (|expected|). See
      http://en.cppreference.com/w/c/atomic:
      
      _Bool atomic_compare_exchange_strong( volatile A* obj,
                                            C* expected, C desired );
      
      The types of the first argument and second argument are different
      (|A| and |C|, respectively). |C| is the non-atomic type corresponding
      to |A|. In the emulations of atomic_compare_exchange_strong(), |C| is
      intptr_t. This implies |A| can only be sig_intptr_t.
