Even a partial, incomplete support of module IEEE_ARITHMETIC would be very
useful and much appreciated:
>From http://gcc.gnu.org/ml/gcc/2008-11/msg00372.html
a) To set an IEEE value (NaN, INF, etc.)
b) Check whether a value is NaN, etc.
and IEEE_VALUE(X, IEEE_QUIET_NAN)
So we wouldn't have to resort to non-standard functions like ISNAN()
(http://gcc.gnu.org/onlinedocs/gfortran/ISNAN.html) anymore.
