    The change to the old decimal code does not show any regressions using
either Mono's test suite (mscorlib, System and System.Data) or the test
suite that we received from Microsoft for Silverlight and Rotor.

     In our internal mailing list, I found a reference to a discussion in
May of 2004 where Atsushi and Uma were discussing all the pending failures
in the test suite, and Atsushi set out to fix both mscorlib as well as
System.Data.   Those correspond to the changes of May 11th 2004.
