Actually, you ran with Cygwin 1.5.13 for this test despite the fact that 
you actually installed 1.5.14 via 'setup.exe' the last time you ran it.
But I expect that's of little consequence.  I could not reproduce the 
problem on W2K Pro or XP Pro with either 1.5.13 or the latest snapshot 
(4/12).  I don't see anything obviously wrong with your configuration 
but there's something going on here.  Do you have a local copy of 'sort' 
in your '/usr/local/bin'?
