I don't have a strong opinion on this.  Probably, the routines should
be in libc.  However, it's probably simple also to put them in libgcc
which contains some arithmetic operations.  Some work in gcc would
be needed in any event to integrate the package.

I found the quad double package at the mpfr site.  However, its double
double differs from the IEEE quad precision representation.  A double double
is a representation using two IEEE doubles.  This is fine as a separate
library but not the IEEE implementation we are looking for.
