I used visual studio 2013 to build the libraries

With dflag -m64 and dub flag --arch=x86_64, this happens


     Running: dub build --arch=x86_64

     ## Warning for package rsdlib ##

     The following compiler flags have been specified in the 
package description
     file. They are handled by DUB and direct use in packages is 
discouraged.
     Alternatively, you can set the DFLAGS environment variable to 
pass custom flags
     to the compiler, or use one of the suggestions below:

     -m64: Use --arch=x86/--arch=x86_64 to specify the target 
architecture
