Hello, Works fine here. I'm running your testcase on:
$ uname -a CYGWIN_NT-5.0 mordor 1.3.20(0.73/3/2) 2003-02-08 12:10 i686 unknown unknown Cygwin It will help if you provide more infomation about your system environment and the version of Cygwin that you are running. To learn how to do this take a look at http://www.cygwin.com/bugs.html, the section named 'Bug reporting guidelines'.
