#11175: signals2, filesystem, probably others fail on clang targeting win32 when
exceptions are disabled
------------------------------+------------------------
 Reporter:  hlandau@…         |      Owner:  bemandawes
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  filesystem
  Version:  Boost 1.57.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------
 To reproduce:
 {{{
   clang -fno-exceptions -std=c++14 reprod.cpp
 }}}
 reprod.cpp:
 {{{
   #include <boost/filesystem.hpp>
   #include <boost/signals2.hpp>
 }}}
 You can target win32 from Linux using wclang
 (https://github.com/tpoechtrager/wclang), though you must have a
 i686-w64-mingw32 environment installed. Substitute 'clang' for 'w32-clang'
 above. This is how I tested; since clang is rather universal as a
 compiler, these errors likely also occur when compiling for win32 on
 win32.

 The documentation for filesystem3 indicates that it should be usable with
 exceptions disabled, so this is a bug.
