bug#14840: Fwd: basename: a faulty warning 'extra operand --test-name' in tests causes test-driver to fail

[Vasiliy]

Dear AutoMake Team,

I have tracked down a problem with 'test-driver'. Look at that:

/usr/share/automake-1.14/test-driver: invalid option: '--log-file=/tmp'
[New Thread 2164.0x19d4]
Usage:
  test-driver --test-name=NAME --log-file=PATH --trs-file=PATH
              [--expect-failure={yes|no}] [--color-tests={yes|no}]
              [--enable-hard-errors={yes|no}] [--] TEST-SCRIPT
The '--test-name', '--log-file' and '--trs-file' options are mandatory.

So, there is a problem with 'test-driver' either because a testsuite
may not provide --test-name=NAME or because --log-file=/tmp or
--log-file=/tmp/delme is wrongly considered an invalid option. It
applies to automake 1.13 as well.

If so, it fails dramatically with messages like this:
...<some_software>/./build-aux/test-driver: line 95:  <PID>
Segmentation fault      (core dumped) "$@" > $log_file 2>&1

Could AutoMake Developers change this behavior, or,
at least, make omitting --test-name not so critical?

Best regards,
Vasiliy
