#995: 'multiply defined symbols' when including <boost/filesystem.hpp> in
different source files
------------------------+---------------------------------------------------
 Reporter:  anonymous   |        Type:  Bugs          
   Status:  new         |   Milestone:                
Component:  filesystem  |     Version:  release 1.34.0
 Severity:  Problem     |    Keywords:                
------------------------+---------------------------------------------------
 When <boost/filesystem.hpp> is included in different source files, the
 linker complains about 'multiply defined symbols'

 Attached: two source files that reproduce the error when compiled and
 linked in the same project.

 boost-1.34.0
 MSVC 7.0
