it seems a 1.7 specific fault.
On cygwin 1.5 it works; I never checked before :-(=20

is it possible that Cygwin-1.7 is fooled by the not like-C
standard output ?

"GFORTRAN_STDOUT_UNIT=E2=80=94Unit number for standard output

This environment variable can be used to select the unit number preconnecte=
d to standard output. This must be a positive integer. The default value is=
 6. "

IT.html#GFORTRAN_005fSTDOUT_005fUNIT
