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

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

"GFORTRAN_STDOUT_UNIT—Unit number for standard output

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