This has been reported to the cygwin list (see
http://cygwin.com/ml/cygwin/2010-03/msg00549.html). In her
answer, Corinna Vinschen states (implicitly) that you cannot assume
that the st_mtime of a pipe is not "artificially" forged.

If i understand correctly the file `gzip.c' lines 625 to 634
(gzip-1.4.tar.gz), a call to `time_t time()' has to be added around.
