I think I've run into a bug concerning "tar" and the use of
windows format paths.  It's not a bug that is difficult to work
around, but it still seems as though it is a bug that someone may
wish to address (in their spare time, of course :-).

I wanted to save a list of files into a tar archive where the
list was created by a windows-based utility that generated
windows-style pathnames.

Just to see if it was "supported" at all, I decided to try it with
1 file first, before attempting the whole archive.

Created file /tmp/tst that contained 1 filename:
c:\WINDOWS\msagent\chars\brocklee.acs

My command line was:
tar cvpf /tmp/tst.tar -T /tmp/tst --ignore-case --no-recursion

My output was:
tar: Removing leading `c:\' from member names
tar: c\:\\WINDOWS\\msagent\\chars\brocklee.acs: Cannot stat: No such 
file or directory
tar: Substituting `.' for empty member name
tar: : Cannot stat: No such file or directory
tar: Error exit delayed from previous errors
----
ls gives:
 > ls -lGg C:\\Windows\\msagent\\chars\\brocklee.acs
-rw-r----- 1 3614596 Jul  5  2002 C:\Windows\msagent\chars\brocklee.acs

Note in "tar", the backslash before the filename wasn't
doubled as were the other backslashes:
    tar: c\:\\WINDOWS\\msagent\\chars\brocklee.acs
                                     ^^

If I edit the input file and add an extra "backslash" before
the filename, like:
c:\WINDOWS\msagent\chars\\brocklee.acs
                         ^ extra backslash

Then tar "works".

Easy workaround is to convert the paths to unix-type paths.
