But wait.  You're mixing advice (Chris's) it seems.  He said @file would
be a solution if you were working outside of Cygwin shells and that 
remounting with -X could be a solution if you were inside.  So it sounds
like you tried both, and perhaps together, but it's unclear whether you
ran your tests from a Cygwin shell prompt, a Windows DOS prompt, or both.
Can you clarify what you tried and where?

Thanks,
