Thanks, I've grabbed a copy.

Ah, Ok, I see.  You just ran strace.  I was hoping you were in gdb or
something.  No matter.  That's Ok.  I'll debug it.

Ah.  No.  I was refering to http://www.cygwin.com/snapshots
You can get a pre-release copy of the latest cygwin before it's
officially released.  Often times this fixes peoples problems until it's
officially rolled out.

One more thing.  Can you send me the output from the 'setopt', 'env' and
'set' commands so I can see what you have set?  Be sure to remove any
sensitive information first.  Thanks!

Sorry, but I'm not familiar with Gmane.  How would I go about CC'ing you
there?
