 Hi,

 with this code
 {{{
 #include <fstream>
 #include <iostream>
 #include <boost/iostreams/filtering_stream.hpp>
 #include <boost/iostreams/copy.hpp>
 #include <boost/iostreams/filter/zlib.hpp>

 int main()
 {
     using namespace std;

     ifstream file("hello.z", ios_base::in | ios_base::binary);
     boost::iostreams::filtering_stream<boost::iostreams::input> in;
     in.push(boost::iostreams::zlib_decompressor());
     in.push(file);
     boost::iostreams::copy(in, cout);
 }
 }}}

 The current trunk compiles. However, if the -std=c++11 or -std=c++14 flags
 are specified with gcc (tested versions 4.9.2 and 5.3.0) the following
 error is displayd:

 Almost the same error shows up when the gzip_decompressor is used to
 replace the zlib_decompressor.

 This bug is also present in the 1.60.0 download.

 Thanks for looking into this,
