I've thought about it.  I know in the past we had weak aliases to do the
support the same way when we had the last name mangling change.  I know those
aliases weren't popular back then.

Part of the reason for asking is I don't have a sense for how library
maintainers use the __float128 and __ibm128 keywords.  Do they treat them as
full fledged types, or are they just convenient ways to compile code with both
names rather than building two modules, with the different long double types?
