Erm, wat? Sorry, but I quite don't understand, what the end-result you want?
Cygwin is installed in userspace. You could even install it in your profile
directory (assuming you're on Vista/W7).

Then you don't have permissions to write to that folder.

Sorry my, is this question regarding Cygwin, or msys?
