/*
    The following predefined macros are used within ACE ifdefs.
    These are defined when using the Cray compilers.  _CRAYMPP
    is defined, for example, if you are running on a Cray T3E
    massively parallel machine.  Moreover, in the case of the T3E,
    _CRAYT3E will be defined.  This is used to determine the
    ACE_SIZEOF defines for primitive types.

    _UNICOS is defined as either the major version of UNICOS being run,
    e.g. 9 or 10 on the vector machines (e.g. C90, T90, J90, YMP, ...)
    or the major+minor+level UNICOS/mk version, e.g. 2.0.3 => 203,
    being run on an MPP machine.

    Summary:

    _CRAYMPP  (defined only if running on MPP machine, e.g. T3E, UNICOS/mk)
    _CRAYT3E  (defined specifically if compiling on a Cray T3E)
    _UNICOS   (defined if running UNICOS or UNICOS/mk)

    Tested on UNICOS 10.0.0.5, UNICOS/mk 2.0.4.57
    Compiles on UNICOS 9.0.2.8, but some tests deadlock
