[Bug fortran/32048] New: max / min and NaN

[tkoenig at gcc dot gnu dot org]

The test program should consistently return
either 2.1 or NaN:

$ cat foo.f90
program main
  real :: nan
  nan = 0.0
  nan = nan / nan
  print *,max(2.1, nan)
  print *,max(nan, 2.1)
end program main
$ gfortran foo.f90
$ ./a.out
   2.100000
            NaN

A lot of compilers seem to get this wrong, as well.
Marking it as an enhancement.
