[svn-r2844] Purpose:

    New Feature
Description:
    Added array datatype tests to the regression tests.  These datatype
    combinations are tested currently:
        1-D array of atomic datatypes
        3-D array of atomic datatypes
        array of array of atomic datatypes
        array of compound of atomic datatypes
        array of compound of array datatypes
        array of VL of atomic datatypes
        array of VL of array datatypes

    Also added a test to verify that the older style compound datatype with
    array fields works correctly.
Platforms tested:
    FreeBSD 4.1.1 (hawkwind)
