I sent the following reply to the ia32-abi list but haven't yet received 
it back from the list - you might want to check if it's stuck in 
moderation somewhere:

I would suggest that rather than using old terms such as "single", 
"double" and "128-bit extended" to describe floating-point formats, and 
rather than referring to "IEEE-754R", the names from IEEE 754-2008 should 
be used.  That is, binary32, binary64, binary128.  (When referring to 
decimal32, decimal64, decimal128 you still need to specify somewhere that 
it's BID rather than DPD.  And you'll still need to refer to 80-bit 
extended since that's not an IEEE interchange format.)
