Yuck! Looks like the compiler is saying that it has bug...

The change which upsets your compiler is
revision 1.15
date: 2003/02/17 07:58:00;  author: vladimir_prus;  state: Exp;  lines: +6 
-4
Use BOOST_STATIC_CONSTANT.

and was made as the result of 
http://article.gmane.org/gmane.comp.lib.boost.devel/16652/
--- the HP compiler did not like the previous version. 

The question is whether you'll be using 2.95.3 by the time next Boost 
version is released? If not, I suggest you just apply the attached
reverse patch. If yes... something more is needed.
