Chao-ying's on vacation this week. AFAIK Chao-ying's code does nothing explicit to support, or not support, C++. The front-end code was based on the Decimal floating point extension, so should currently behave in a similar fashion to that with regards C++.

Annex F (page 96) of the N1169 spec (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1169.pdf) does give some "guidelines" for C++ usage, but only a very hand-wavy couple of paragraphs. I guess we can ask the committee members if there is any work going on in this area.
