ios_base_storage.cc (test02): Set exception mask.

2003-03-06  Jerry Quinn  <jlquinn@optonline.net>

	* testsuite/27_io/ios_base_storage.cc (test02): Set exception
	mask.  Test setting small-numbered pword and iword slots.  Test
	behavior at limit of numeric_limits::max.  Check that values are
	still good after failures.
