Proposed resolution:

Change [atomics.syn], header <atomic> synopsis as indicated:

namespace std {
  [..]
  // 29.8, fences
  extern "C" void atomic_thread_fence(memory_order);
  extern "C" void atomic_signal_fence(memory_order);  
}

Change [atomics.fences], p. 5 and p. 6 as indicated:
```
extern "C" void atomic_thread_fence(memory_order);
```
5 Effects: depending on the value of order, this operation: [..]
```
extern "C" void atomic_signal_fence(memory_order);  
```
6 Effects: equivalent to atomic_thread_fence(order), except that synchronizes with relationships are established only between a thread and a signal handler executed in the same thread.

Addresses US-179

The fence functions ([atomics.fences] p.5 + p.6) should be extern "C", for C compatibility.
