{ ***** Setup Default Compiler Variables *****}

{
   OTKERNEL is used to indicate whether the code is being built
   for the kernel environment.  It defaults to 0.  If you include
   "OpenTransportKernel.h" before including this file,
   it will be 1 and you will only be able to see stuff available
   to kernel code.
   As we've included "OpenTransport.h" and it defaults this variable
   to 0 if it's not already been defined, it should always be defined
   by the time we get here.  So we just assert that.  Assertions in
   header files!  Cool (-:

   module_info is aligned differently on 68K than
   on PowerPC.  Yucky.  I can't defined a conditionalised
   pad field because a) you can't conditionalise specific
   fields in the interface definition language used to
   create Universal Interfaces, and b) lots of code 
   assigns C structured constants to global variables
   of this type, and these assignments break if you
   add an extra field to the type.  Instead, I
   set the alignment appropriately before defining the 
   structure.  The problem with doing that is that
   the interface definition language doesn't allow
   my to set the alignment in the middle of a file,
   so I have to do this via "pass throughs".  This
   works fine for the well known languages (C, Pascal),
   but may cause problems for other languages (Java,
   Asm).

    QOS type definition to be used for negotiation with the
    remote end of a connection, or a connectionless unitdata request.
    There are two type definitions to handle the negotiation 
    process at connection establishment. The typedef dl_qos_range_t
    is used to present a range for parameters. This is used
    in the DL_CONNECT_REQ and DL_CONNECT_IND messages. The typedef
    dl_qos_sel_t is used to select a specific value for the QOS
    parameters. This is used in the DL_CONNECT_RES, DL_CONNECT_CON,
    and DL_INFO_ACK messages to define the selected QOS parameters
    for a connection.

    NOTE
    A DataLink provider which has unknown values for any of the fields
    will use a value of DL_UNKNOWN for all values in the fields.

    NOTE
    A QOS parameter value of DL_QOS_DONT_CARE informs the DLS
    provider the user requesting this value doesn't care 
    what the QOS parameter is set to. This value becomes the
    least possible value in the range of QOS parameters.
    The order of the QOS parameter range is then:

        DL_QOS_DONT_CARE < 0 < MAXIMUM QOS VALUE

    DLPI interface primitive definitions.

    Each primitive is sent as a stream message. It is possible that
    the messages may be viewed as a sequence of bytes that have the
    following form without any padding. The structure definition
    of the following messages may have to change depending on the
    underlying hardware architecture and crossing of a hardware
    boundary with a different hardware architecture.

    Fields in the primitives having a name of the form
    dl_reserved cannot be used and have the value of
    binary zero, no bits turned on.

    Each message has the name defined followed by the
    stream message type (M_PROTO, M_PCPROTO, M_DATA)
