        Variable mempool initializers may refer to external

        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 vpool1\[2000\];'

        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   "

        Variable block memory pools should be statically

        initialized: enter a list of initializers

        separated by commas, one per line.

        An initializer is

        'CYG_UIT_MEMPOOLVAR(ADDR,SIZE)'

        where addr is the address of memory to manage, and

        size is the total size of that memory.

        If create and delete operations are supported,

        initializers of the form

        'CYG_UIT_MEMPOOLVAR_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 variable pools specified."
