            The number of fixed mempools initially created.
            This number should not be more than the number
            of fixed mempools in the system, though setting
            it to a large value to mean 'all' is acceptable.
            Initially, only fixed mempools numbered from
            1 to this number exist;
            higher numbered ones must be created before use.
            Whilst all mempools must be initialized to tell
            the system what memory to use for each pool,
            it is only useful to initialize the blocksize of
            fixed mempools up to this number;
            the blocksize for higher numbered ones
            will be defined when they are created."

        Fixed mempool initializers may refer to external
        objects such as memory for the pool to manage.
        Use this option to define or declare any external
        objects needed by the pool's static initializer below.
        Example: create some memory for a mempool using
        'static char fpool1\[2000\];'
        to set up a chunk of memory of 2000 bytes.
        Note: this option is invoked in the 'outermost' context
        of C++ source, where global/static objects are created;
        it should contain valid, self-contained, C++ source."

    description   "
        Fixed block memory pools should be statically
        initialized: enter a list of initializers
        separated by commas, one per line.
        An initializer is
        'CYG_UIT_MEMPOOLFIXED(ADDR,SIZE,BLOCK)'
        where addr is the address of memory to manage,
        size is the total size of that memory, and
        block is the block size for allocation by the pool.
        If create and delete operations are supported,
        initializers of the form
        'CYG_UIT_MEMPOOLFIXED_NOEXS(ADDR,SIZE)' should be
        used for pools which are not initially created, to tell
        the system what memory to use for each pool.
        Note: this option is invoked in the context of a
        C++ array initializer, between curly brackets.
        Ensure that the number of initializers here exactly
        matches the total number of fixed pools specified."
