+
+       * src/atomic_ops/sysdeps/gcc/x86.h (AO_double_compare_and_swap_full):
+       New function (only if __x86_64__) implemented using GCC built-in
+       __sync CAS primitive available for x32.
+       * src/atomic_ops/sysdeps/gcc/x86.h
+       (AO_HAVE_double_compare_and_swap_full): New macro (for x32 only).
+       * src/atomic_ops/sysdeps/gcc/x86.h
+       (AO_compare_double_and_swap_double_full): Implement using
+       double_compare_and_swap_full instead of cmpxchg8b for x32 (since
+       x86_64 has cmpxchg and cmpxchg16b but not cmpxchg8b).

+
+       * src/atomic_ops.h: Fix typos in comments (update generalize.h
+       filename).
+

+
+       * src/atomic_ops.c (AO_pause): Fix millis value (passed to Win32
+       Sleep) for the case of 'n' argument in range between 12 and 21,
+       inclusive if AO_USE_WIN32_PTHREADS (sleep for 1 ms in this case).
+       * src/atomic_ops_stack.c (AO_pause): Evaluate 'msecs' value using the
+       same algorithm as in atomic_ops.c (Win32 only).
+

+
+       * src/atomic_ops_stack.c (dummy): Define as static (to make symbol
+       without AO_ prefix visible only within this file); initialize to 1
+       (same as in atomic_ops.c, so that AO_spin would never really alter
+       its value).

+
+       * src/atomic_ops.h: Fix 'load' primitive name in comment (replace
+       AO_load_release_read with AO_load_acquire_read).

+       (AO_compare_double_and_swap_double_full): Test (define if)
+       AO_HAVE_compare_double_and_swap_double_full macro instead of
+       AO_HAVE_compare_double_and_swap_double.

+
+       * src/atomic_ops/sysdeps/standard_ao_double_t.h (double_ptr_storage):
+       Define as "unsigned long long" instead of __m128 for gcc/x32 (i.e.,
+       ILP32 on x86_64); update and reformat comment.

+       * src/atomic_ops.h: Include gcc/x86.h instead of gcc/x86_64.h if
+       gcc/x32 (i.e., GCC (or Intel compiler), __x86_64__ is defined, and
+       __ILP32__ is defined) to have AO_compare_double_and_swap_double_full
