Changes to get the unix code compiling on OSX

    * %llu vs %lu is an OSX vs Linux formatting issue
    * redefinition of structs is gnu11
    * casting (machine_uint_t*) when necessary to avoid array warnings

    Haven't changed the nlrx86.s assembly, which is why I'm
    pushing this as a branch rather than a pull req to master
