This function is not part of the public interface,  but Nanomsg expects it to be called before any subsystems have been intiailized.
Normally, this happens via linking with libNanomsgmain, but since that doesn't happen when using Derelict, then the loader must
load this function and call it before the load method returns. Otherwise, bad things can happen.
