Really?  I thought the only good thing about Itanium was its native
support for IEEE 128-bit floating point.

We had to do BASIC/REAL_SIZE=SINGLE, which I believe gives you F_FLOAT
rather than S_FLOAT.  I forget what broke; possibly we could have
avoided this with a data conversion effort, but floating point was very
rare in the applications, which mostly used decimal, so it didn't seem
worth the effort.
