The final addition (cur += step) may overflow, so use size_t for "cur".
"cur" is always positive (even for negative steps), so it is safe to use
size_t here.

This test case needs "signed short" bitfields, but the
IBM XLC compiler (on AIX) does not support this.
Skip the code and test when AIX and XLC are used.
Use __xlc__ as identifier to detect the XLC compiler.
Raise ValueError OverflowError in case of a negative
_length_ in a ctypes.Array subclass. Also raise TypeError
instead of AttributeError for non-integer _length_.
