Since most other compilers support ieee_arithmetic now, the lack of support in
gfortran is becoming a portability issue. Simple test case with 4.6.1:
> cat t1.f90
program test
use,intrinsic :: ieee_arithmetic
real :: x
read *, x
if (ieee_is_nan(x)) then
print *, "Nan"
else
print *, "Not NaN"
end if
end program test
> gfortran t1.f90
t1.f90:2.35:
use,intrinsic :: ieee_arithmetic
1
Fatal Error: Can't find an intrinsic module named 'ieee_arithmetic' at (1)
