template that uses same name as SS macro

     Type:  Bugs          |      Status:  new          
Milestone:  Boost 1.42.0  |   Component:  serialization
  Version:  Boost 1.41.0  |    Severity:  Showstopper  
 Keywords:                |  
--------------------------+-------------------------------------------------
 /usr/include/sys/regset.h on Solaris 10 contains:

 #define SS              18      /* only stored on a privilege transition
 */

 boost/serialization/static_warning.h contains:

 template<int i>
 struct SS {};

 The unavoidable combination produces the compilation error:
   boost/serialization/static_warning.hpp:96: error: expected unqualified-
 id before numeric constant
 The combination is unavoidable because regset.h is pulled in by headers
 included by other boost headers.

 Solution: rename SS template to something else (e.g., boost_SS).

 Although the BSW macro doesn't conflict with anything I'm aware of, it
 would be prudent to rename that macro (perhaps to
 BOOST_SERIALIZATION_STATIC_WARNING), to avoid future conflicts on other
 platforms.
