Re: CVS on VMS mailing list ?

I posted a patch against 1.11 for the VMS rename command to cvs-bugs a month or 
two ago.  My message got no response whatever, so I'm not certain where to take 
it from here.

The issue I found is that when using a repository with "watch on", CVS will not 
update any changed files, since the files in the local repository are read 
only.  My patch just turns on write permission before the new file is 
"rename()"ed onto the existing
file name, then replaces the original permissions.

(Searching my sent mail folder ...)
