No, I haven't tested it, but given the trivial nature of the functions (3-5
instructions), it is sufficient to simply check the instructions generated.
Using objdump I find that they all have correct assembly language code. Any x86
programmer may verify the code generated below:

00000060 <interlocked_cmpxchg>:
  60:    8b 44 24 0c              mov    0xc(%esp),%eax
  64:    8b 4c 24 08              mov    0x8(%esp),%ecx
  68:    8b 54 24 04              mov    0x4(%esp),%edx
  6c:    f0 0f b1 0a              lock cmpxchg %ecx,(%edx)
  70:    c3                       ret   

0000007c <interlocked_cmpxchg_ptr>:
