AMTAR brokenness

- Subject: AMTAR brokenness
Recent versions of GNU tar correctly use the "-o" option. This breaks
any project with path lengths >100. Previously GNU tar incorrectly
produced a POSIX tar file with "-o", but now it produces a crippled
UNIX v7 tarfile.
PR/414 has been filed against automake. A patch against automake
1.8.3 follows, which uses the correct --format=posix syntax. Both the
current and patched forms do rely on GNU tar. A configure check to
check for GNY tar might be better. Either way, GNU tar should *not*
be given the "-o" option, since it causes horrible breakage.
Regards,
Roger
