------- Comment #9 from arnaud02 at users dot sourceforge dot net 2007-08-20 12:28 -------
Adding -finit-real=nan (http://gcc.gnu.org/ml/fortran/2007-08/msg00408.html) is
a real bonus for gfortran.
Any chance to add "-finit-real=snan" to set "Signalling NaN" ?
A SNaN cannot be the result of any arithmetic operations, hence a good choice
for a unset pattern. The NAG compiler uses SNaN when using "-nan".
