New description:

 The following code fails to compile with intel-linux-12.1.3.0x


 {{{
           typename std::basic_ostream<CharT, Traits>::sentry opfx(os);
           if (opfx)
           {
 }}}

 with the message

 {{{
 ../../../boost/chrono/io/duration_io.hpp(130): error: expression must have
 bool type (or be convertible to bool)
             if (opfx)
 }}}

 even if sentry defines an explicit bool conversion.

 A workaround to this issue is needed.
