I don't think that glibc is wrong by defining __STDC_IEC_559__ (computing in an
extended type is allowed by the IEEE-754 standard) as long as FLT_EVAL_METHOD is
correctly set. The real problem is that intermediate results in extended
precision are not converted back to double after a cast or an assignment; this
is required by the C standard, whether __STDC_IEC_559__ is defined or not.
