-// On some platforms ~mutex has been made trivial and the definition is only
-// provided for ABI compatibility.
-//
-// In order to avoid ODR violations within libc++ itself, we need to ensure
-// that *nothing* sees the non-trivial mutex declaration. For this reason
-// we re-declare the entire class in this file instead of using
-// _LIBCPP_BUILDING_LIBRARY to change the definition in the headers.
