Check your mounts.  See if you have /tmp mounted in textmode.
Also, check if the filesystem you are running the script from is mounted
in textmode or not and weither the CYGWIN env var has textmode on binmode
set.  Try playing around with textmode & binmode.  Read the cygwin doc
concerning text translation:
