I don't really know, but I can guess. Gnu tar does not compress the
archives itself; it runs gzip and sends the data to it through a
pipe. It seems that on MSDOS this, for some reason, wouldn't
work. Maybe MSDOS does not support pipes, or has some other similar
limitation. (NT should have pipes, but presumably that version is made
for MSDOS). Of course, make sure you have gzip installed and in the
path (although the error message indicates that it's not because of a
missing gzip).

Obvious workaround:

gtar cvf backup.tar *.avt
gzip backup.tar
