I think libgfortran does not assume any specific rounding and should
work in principle correctly independing of the rounding. Though there
might be bugs, due to the implicit assumption of one way of rounding.
FX added several fall back implementations of C99 functions.
Those, I suspect, assume round-to-nearest, but I have no
intention of proving this.
