The library changed in 1.44, you now need to explicitly specify if you
want the file_descriptor to be automatically closed.
namespace io = boost::iostreams;
io::stream<io::file_descriptor_source> in(
handle, io::close_handle);
And the handle will be closed when in is destructed, or you call
'in.close()'. Or if you want to close it yourself:
io::stream<io::file_descriptor_source> in(
handle, io::never_close_handle);
// later...
close(handle);
Note that with 'never_close_handle', the handle isn't closed even if
you call the 'in.close()'. This is because otherwise some generic code
can call 'in.close' and close the file when it shouldn't be closed.
