[Bug-tar] paxutils/tests/genfile.c lint removal

[Paul Eggert]

I installed this to fix some warnings with GCC 4.1.1:

2006-08-07  Paul Eggert  <address@hidden>

        * tests/genfile.c (reg_action): Return void, not int.
        (generate_simple_file, exec_command): Remove unused var.
        (print_stat): Avoid GCC warning about uninitialized var.
