 When building libs/log/src/settings_parser.cpp with Solaris Studio 12.3,
 I'm getting the following errors.  FYI: I changed convert.hpp by applying
 the fix suggested in ticket #7513.

 {{{
 "./boost/fusion/sequence/convert.hpp", line 23: Error: apply is not a
 member of
 boost::fusion::extension::convert_impl<boost::fusion::struct_tag>.
 "./boost/fusion/mpl/push_front.hpp", line 28:     Where: While

 /* More errors afterward, but they appear to be repeats of existing errors

 }}}

 The following change(s) will get rid of the errors:

 {{{
  208: #ifdef BOOST_LOG_USE_CHAR
 -209: template BOOST_LOG_SETUP_API basic_settings< char > parse_settings<
 char >/*...*/
 +209: template<> BOOST_LOG_SETUP_API basic_settings< char >
 parse_settings< char >/*...*/
  210: #endif
  211: #ifdef BOOST_LOG_USE_WCHAR_T
 -212: template BOOST_LOG_SETUP_API basic_settings< wchar_t >
 parse_settings< wchar_t >/*...*/
 +212: template<> BOOST_LOG_SETUP_API basic_settings< wchar_t >
 parse_settings< wchar_t >/*...*/
  213: #endif
 }}}
