----------------------------------+-----------------------------------------
 When trying to compile a testcase which is usually used to check whether
 boost iostreams are usable, I get a compile error (has some path
 constructor recently been added?)

 I am using release branch [64222]

 $ cat test.cpp
 #include <boost/iostreams/device/file_descriptor.hpp>

 int
 main ()
 {
   boost::iostreams::file_descriptor fd(0);
   fd.close();
   return 0;
 }
 $ g++ test.cpp -I/home/staff/ps/include/boost-release/
 -L/home/staff/ps/lib -lboost_iostreams
 /home/staff/ps/include/boost-
 release/boost/iostreams/device/file_descriptor.hpp: In constructor

 std::_Ios_Openmode) [with Path = int]’:
