The current cygwin1-1.5.9.dll and snapshots up to 20040406 have exhibited an intermittent problem with cat: the error msg "input file is output file" has been presented during a long sequence
cat f.1 f.2 f.3 ... f.n > f.target when there is in fact no coincidence of names. This was reported earlier at //www.cygwin.com/ml/cygwin/2004-03/msg01211.html (also with 1.5.9). The problem seems to depend in some subtly inexpressible way (otherwise I would have sent a test case) on the contents of f.1 .. f.n and the name of f.target. Well, at least with the examples I have tried (many) this problem is cured with snapshot 20040409. And with 20040411. Thank you.
