But the "normal" tar has a blocking option. Okay, WinNT won't
automagically determine block size; even the Unixes I've worked with
will only figure it out if you tell it to use a block size bigger than
the actual size. So why won't the standard POSIX (or whatever) calls in
GNU tar correctly set the block size in cygwin? Why do we need a
specially hacked version of tar/cpio/dd/mt/etc.? I would think the
correct way to address this problem would be to hide the details of the
"Windows way" behind the standard "Unix way." Isn't that the idea of a
Unix-emulation layer?

BTW - While it is not a big deal in this case and I appreciate your
help, my original message was sent directly to you, Corinna, and not to
the list. Since you did not ask for my permission, to copy my personal
message to this list is not in the best of form.
