indirection. All uses updated.
(avoided_name_table, add_avoided_name)
(is_avoided_name): Remove.
* src/update.c (update_archive): Change algorithm.
Instead of adding unmodified files to the avoided_name
table, create namelist so that it contains only
modified files.

(parse_opt): Use *_PROGRAM defines instead of hardcoded
program names.
This adds --with-gzip, --with-bzip2 etc. switches to the configure, so that

not a pointer to it. Date is a copy as well, hence the `const' is
taken away.

This makes two pax archives binary equivalent if they
have the same contents and care is taken to make extended
headers otherwise reproducible, e.g. by using:
--pax-option=exthdr.name=%d/PaxHeaders/%f,atime:=0
Proposed by Michael D. Adams <mdmkolbe@gmail.com>.
* src/common.h (start_private_header): Take time_t as 3rd param.
(xheader_write): Likewise.

instead of setting program_name directly.

instead of setting program_name directly.
* tests/Makefile.am (TESTSUITE_AT): Add remfiles01.at
and remfiles02.at.

* src/common.h (MODE_FROM_HEADER): Take additional argument.
(mode_from_header): Likewise.
* src/create.c (mode_to_chars): Store all mode bits if

Changes to src/create.c and src/incremen.c are partially

Take advantage of the name->cmdline to set top_level argument
during incremental backups.

Do not bail out if a no-top-level file disappears during incremental
backup, use file_removed_diag instead.
(dump_filed): top_level is bool.
* src/incremen.c (update_parent_directory): Silently ignore
ENOENT. It should have already been reported elsewhere.
(scan_directory): Use dir_removed_diag to report missing directories.

in the resulting archive is the same, whatever their order
on the command line. It also fixes the operation of
--listed-incremental -C.
