Hello,
please, could you consider applying the attached patch? The problem is
when tar is invoked with --format option, such that:
(format != posix && format != default)
In such case it is impossible to change file attributes while
extracting/listing by --pax-option, e.g.:
tar --format=gnu --pax-option="mtime:={now}" -xvf test.tar
Note: I tried to prepare macro in src/common.h rather then fixing it
directly in src/tar.c, because I'd like to reuse this macro later on (if
possible) in extended attributes proposal.
