* dlfcn/default.c (main): Cast dlsym loaded value to same type as main.
Address passed to test_in_mod1 and test_in_mod2 without casting.
* dlfcn/defaultmod1.c: Change prototype of test_in_mod1.
(test_in_mod1): Cast dlsym loaded value to same type as mainp.
* dlfcn/defaultmod2.c: Change prototype of test_in_mod2.
(test_in_mod2): Cast dlsym loaded value to same type as mainp.

* sysdeps/sparc/sparc32/bits/atomic.h (__sparc32_atomic_lock):
Renamed to...
(__sparc32_atomic_locks): ...this. Change into 64-byte array.
(__sparc32_atomic_do_lock, __sparc32_atomic_do_unlock): Add addr
argument. Select one of 64 locks from address bits.
(atomic_compare_and_exchange_val_acq,
atomic_compare_and_exchange_bool_acq): Pass memory address to
__sparc32_atomic_do_{,un}lock.
