This looks suspiciously like you need to link with the correct type of library containing networking stuff. The implicitly declared htonll functions is also a warning sign that there is something fishy going on. Perhaps you need to do something to explicitly ask for 32 bit mode, or perhaps 32 bit mode is for backwards compatibility only and can't be used as a compilation target.
