Dana Robinson 35d6091ab7
Cleans up a couple of MSVC warnings in testhdf5 (#475)

**
** test_select_hyper_checker_board_dr__verify_data():
**
** Examine the supplied buffer to see if it contains the
** expected data. Return TRUE if it does, and FALSE
** otherwise.
**
** The supplied buffer is presumed to contain the results
** of read or writing a checkerboard selection of an
** n-cube, or a checkerboard selection of an m (1 <= m < n)
** dimensional slice through an n-cube parallel to the
** fastest changing indices.
**
** It is further presumed that the buffer was zeroed before
** the read, and that the n-cube was initialize with the
** natural numbers listed in order from the origin along
** the fastest changing axis.
**
** Thus for a 10x10x10 3-cube, the value stored in location
** (x, y, z) (assuming that z is the fastest changing index
** and x the slowest) is assumed to be:
**
** (10 * 10 * x) + (10 * y) + z
**
** Thus, if the buffer contains the result of reading a
** checker board selection of a 10x10x10 3-cube, location
** (x, y, z) will contain zero if it is not in a checker,
** and 100x + 10y + z if (x, y, z) is in a checker.
**
** If the buffer contains the result of reading a 3
** dimensional slice (parallel to the three fastest changing
** indices) through an n cube (n > 3), then the expected
** values in the buffer will be the same, save that we will
** add a constant determined by the origin of the 3-cube
** in the n-cube.
**
** Finally, the function presumes that the first element
** of the buffer resides either at the origin of either
** a selected or an unselected checker.
