#11707: Locale facets have hidden visibility

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  date_time
  Version:  Boost 1.59.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------
 When the application or another library is compiled with hidden visibility
 by default, Boost.DateTime IO facets end up having hidden visibility as
 well. This breaks libstdc++ locale operations, such as `has_facet` and
 `use_facet`, as these operations are based on `dynamic_cast`.

 Boost.DateTime should work regardless of the default visibility mode the
 application chooses. All facet types, as well as the types that can be
 used in their template parameters, should be marked with
 `BOOST_SYMBOL_VISIBLE`.
