Well, first off, it can't be the "same gnuwin environment" because they 
are on different hosts.

What does the mount tables of each host look like?  Do you have Sergey's 
patches installed on each host?  What are the environment variables of 
each host?  Etc...

Now that I've learned a bit of history, thanks to Fergus Henderson, my 
best guess is that the file contains line terminators of \r\n.  One host 
runs the file because it's mounts are text!=binary.  The other doesn't 
because it's mounts are text=binary.
