There are 2 problems with __float128 runtime support if it is different
from single, double and long double:
1. __float128 isn't enabled even if gcc supports it.
2. __float128 I/O isn't supported even if __float128 is enabled.
My patch:
http://sources.redhat.com/ml/libc-alpha/2004-05/msg00049.html
tried to address those.
