Ok.

Post scriptum:

I find the following quite puzzling. For "print '(F0.1)',huge(1.0)",
gfortran prints:
  340282346638528859811704200000000000000.0
whereas ifort prints
  340282346638528859811704183484516925400.0
and NAG, Sun, g95 print:
  340282346638528859811704183484516925440.0
which matches the exquation/tree-dump:
huge = ((1-(1/2)^24)2^128) = 340282346638528859811704183484516925440

Reading any of these numbers with any of these compilers gives huge(r)
thus one should probably not worry much about it.
