    build - Adjust _CMSG_ALIGN() for compatibility
    
    * The argument to _CMSG_ALIGN() is commonly unsigned, fix compiler
      warnings by making the alignment constants unsigned.
    
    * Also take a page from FreeBSD and cast the (n) argument to an
      unsigned quantity (size_t).
    
    * Note that the alignment code is still hardwired to 4 bytes,
      and will eventually have to be changed to something more portable.
      For now do not change it as doing so would introduce an ABI
      incompatibility.
