self checks: relax tests on cleanup
Some find(1) implementations have problems operating recursively on
directories having subdirectories with null permissions, even when
the permissions of such subdirectory should be fixed by find before
it descends into them; for example, with this setup:
% mkdir a a/b
% chmod 000 a/b
a command like this:
% find a -type d ! -perm -700 -exec chmod u+rwx '{}' ';'
fails with this diagnostic on MacOS X 10.7:
find: a/b: Permission denied
and with this diagnostic on Solaris 10:
find: cannot read dir a/b: Permission denied
The problem is that our self checks were simply demanding too much
from our cleanup trap: our tests never use subdirectories with null
permissions, so it doesn't matter if the cleanup trap fails to
handle those. Just relax the self checks to avoid such useless
testsuite noise.
* tests/self-check-cleanup.tap: Only try directories missing
write permissions, not with null permission. That should be
enough for our usages.

spy: "rm -f" and "rm -rf" without args are portable
According to recent testing by Eric Blake, it seems that all
non-museum rm(1) implementations don't complain if called without
file operands, *if* the '-f' option is used. This behaviour will
likely be mandated by future versions of the POSIX standard as
well.
We'd like to start assuming this rm(1) behaviour in future Automake
releases, in order to simplify some automake-provided cleanup rules.
So, for the moment, we add a new "spy" test in our test suite, to
try ensuring that all the rm(1) implementation we encounter "in the
wild" truly behaves as expected in this regard.
For more references, see this discussion on the bug-autoconf list:
<http://lists.gnu.org/archive/html/bug-autoconf/2012-02/msg00002.html>
which sprang from coreutils bug#10819:
<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10819>
and brought to the POSIX issue#542:
<http://austingroupbugs.net/view.php?id=542>
which has been accepted and will ensure that future version of the
POSIX standards will mandate that 'rm' shouldn't complain if called
without file operands, when the '-f' option is in use.

automake: new option 'serial-tests'
Currently, automake offers a 'parallel-tests' option to enable the
use of the parallel testsuite harness in the generated Makefiles,
but no option to explicitly state the intention of using the older

This makes the parallel test harness seems like a second-class

importantly, it will prevent us from making the parallel harness
be the default one in future automake versions, since the users
of the serial harness would then have no way to instruct automake

tests: another spurious failure with older autoconf fixed
* tests/aclocal8.test (configure.in): Also call 'AC_INIT', it's
required by some older autoconf versions (e.g., 2.63).
* tests/acloca15.test: Likewise. Add trailing ':' command since
we are at it.

tests: fix spurious failure with older autoconf
* tests/conffile-leading-dot.test: Relax grepping of 'config.status'
stderr, to cater for older autoconf. Issue revealed by a failure
with autoconf 2.63 on Cygwin 1.5.25.
