 On 2008-11-12 Changeset 49704 was submitted to the boost trunk for
 boost/type_traits/intrinsics.hpp to fix a 32-bit Linux alignment_of
 failure.

 Part of the change was to check for {{{"#if !defined(unix)"}}}.  If
 intrinsics.hpp is compiled on 32-bit Linux using GCC 4.3 with the
 -std=c++98 command-line argument then this fix will not work as expected.
 The -std=c++98 argument argument informs the compiler to define
 {{{"__unix__"}}} but not {{{"unix"}}}.

 If believe the original fix needs to be updated to check for {{{"#if
 !defined(__unix__)"}}}.
