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. H.J.
