Re: Cygwin OCFS support (or lack of)

["doron cs" <doroncs at gmail dot com>]

I have OCFS access as much as you want
What I do not have right now (and it will take time until i get it) is
a cygwin development environment on my Win2003 servers .
If you will send me binaries I will be extatic to run them and strace them
until I will setup my Cygwin development systems .
