Bug in the new code recognizing invalid path preceeding a ".." path
component.  It ignores one leading slash in case of UNC paths and so
accidentally checks for /server/share/path rather than //server/share/path.

I fixed that in CVS and I just generated new x86 and x86_64 snapshots.
Please take your pick at http://cygwin.com/snapshots/ and report back if
you still see problems with it.


Thanks,
Corinna
