Fw: [cxx-abi-dev] Decimal Floating Point mangling was(Fw: [cxx-abi-dev] C++0x: Mangling of rvalue reference type)s

[Michael Wong]

While I believe this encoding is slightly better, unfortunately, we have 
productized this based on the earlier agreement (although Mark did advise 
me to send a braodcastl) that the encoding was acceptable. We also believe 
GNU has also chosen the same encoding based on our advice. So we have 
released a first product out based on this and changing it now would lead 
to binary incompatibility. I realize now I should have sought the opinion 
of this group and for that I deeply apologize.

I realize this is not the best encoding, but many other single letter 
encoding do not represent their actual names. We agree that this is not 
ambiguous. So for the sake of precedence, can we agree on the original 
encoding?
