Log Message:
Update to 1.01:
  * Five years have passed since the last release: completely updated
    the Autoconf build system, enable Autoconf large file support.
  * Warn about a compressed file's trailing zero bytes only if in
    verbose mode (for compatibility with recent versions of GNU tar).
  * Don't be too strict in favoring stdin - using `--no-stdin' should not
    be necessary any longer.
  * Added option `-P' to save/restore the path name of a compressed file.
  * Added option `--crc32' to use a crc32 instead of a adler32 checksum.
  * Fixed an assertion that could happen in very rare cases.
