But you are not done with commenting out the assertion.

The programs 'printf', 'seq', and 'sort' assume that a 'double' number
can be losslessly converted to a 'long double'. On platforms where this
is not the case, you will need to use a
   union { double d; long double ld; }
instead of a "long double" value. Otherwise the programs can not read
and compute with numbers between 1e-307 and 1e-292.
