Gerv,

I wonder if it's related to CVS's inability to remove lock directories
from some SMB shares, which I reported back in 2003...  That seems to be
hard to track, because different SMB shares have subtly different access
settings.  In any case, first try adding "nosmbntsec" to your $CYGWIN, and
see if it helps.  I also found that, when using Samba from AIX (don't know
about Linux/Windows), it helps to add the group that owns the repository
to /etc/group, and add the Cygwin user to that group.
