Package: mc
Version: 4.6.0-4.6.1-pre4-2
Midnight Commander does handle tar archives bigger than the magic 2GB
size incorrectly.
I appended a patch fixing the problem. Since it includes changes in the
VFS of the Midnight Commander, changes made to other virtual filesystems
are included too. Those however are not tested and mostly will not make
them bypassing the limit.
With best regards
Michael M?ller
