Comment (by jhunold):

 Revision https://svn.boost.org/trac/boost/changeset/75544 just broke my
 clang builds.
 The correct solution would be to either
 - use #if defined(BOOST_CLANG) see container_fwd_guarded.diff
 - change "class" to struct see containner_fwd_simple.diff

 The interesting thing is that container_fwd.hpp contains a msvc-
 suppression for struct/class mismatch: line 104ff:
 {{{
 #if defined(BOOST_MSVC)
 #pragma warning(push)
 #pragma warning(disable:4099) // struct/class mismatch in fwd declarations
 #endif
 }}}

 So the "correct" solution depends on how the corresponding standard
 library declares struct or class "complex". At least the guarded approach
 prevents clang from emitting a warning.
