tests: remove t/parallel-tests-many.sh (fixes spurious failure)

That test was checking for automake#7868 "parallel-tests and command-line
length limit issue".  That bug is still open, and the tests was xfailing.

What concerns us is that the test was also causing an annoying problem.
On Solaris 10, it produced a '.log' file with two overly-long lines (more
than 1 million characters long!) and that was causing the test harness to
experience spurious failures, with Solaris XPG4 awk complaining that:

 /usr/xpg4/bin/awk: line 0 (NR=734): Record too long (LIMIT: 19999 bytes)

A little consideration shows that the bug#7868 checked by the culprit
test cannot be solved "by accident", e.g., by another bug fix or some
simple refactoring, so there is little added value in keeping the xfailing
test for it, if this causes other problems (and we've seen it does).

So we just remove the test.  In case we ever manage to fix the bug in
mainline automake, we can copy over the similar test(s) from Automake-NG,

tests: don't use C instead of C++ compiler on case-insensitive platforms

This change fixes automake bug#11893 and bug#10766.

On at least Cygwin and Mac OS X 10.7, the file system where the system
compilers are located can be case-insensitive, so that looking for a
program named 'CC' might actually find the C compiler in /usr/bin/cc.

Now, the Automake configure script looks for a C++ compiler named 'CC'
before looking for more obvious names like c++ or g++ (that is done to
increase testsuite "coverage in the wild", e.g., preferring, on Solaris,
the Sun Studio C++ compiler /usr/bin/CC over the GNU C++ compiler).

Since the checks done in AC_PROG_CXX are apparently not strict enough
to rule out C compilers like those from GCC or Clang (which are smart
enough to recognize if a file has a C++ extension, passing it to the
C++ front end) the testsuite might end up using a C compiler where a
C++ one is expected, with some subtle bad consequences.

* configure.ac: Don't look for a C++ compiler named 'CC' if the
"top-level" file system(s) (where /bin and /usr/bin are) are detected
to be case-insensitive.

subdirectories read-only; then, in order to create the '_inst' and
'_build' subdirectories in there (used by the rest of the recipe) we
made the top-level $(distdir) *world-writable* for an instant (the
time to create those two directories) before making it read-only
again.

Making that directory world-writable (albeit only briefly) introduced a
locally exploitable race condition for those who run "make distcheck" with
a non-restrictive umask (e.g., 022) in a directory that is accessible by
others.  A successful exploit would result in arbitrary code execution
with the privileges of the user running "make distcheck" -- game over.
Jim Meyering wrote a proof-of-concept script showing that such exploit is
easily implemented.

This issue is similar to the CVE-2009-4029 vulnerability:
<http://lists.gnu.org/archive/html/automake/2009-12/msg00012.html>

* lib/am/distdir.am (distcheck): Don't make $(distdir) world-writable,
not even for an instant; make it user-writable instead, which is enough.

tests init: don't automatically re-execute tests with a POSIX shell

I've unwittingly broken support for that feature *again* in some of
my recent testsuite tweaking.  In this case, the re-execution code
works correctly when the tests are executed with a POSIX shells, but
breaks when they are invoked by an old-style Bourne shells (e.g.,
/bin/sh on Solaris).

It's time to face it: that feature is too much brittle, and too seldom
used (because the Makefile takes care of running the tests with the
correct shell anyway, so that a breakage is only experienced when
running the tests by hand).  It just don't remain working for long, not

when we'll try to move part of our testsuite framework to Gnulib, or a
similar project).

So, instead of trying to be extra-smart and automatically re-execute the
tests with the correct shell, we now offer a simple wrapper script that
the user can employ to run the test scripts with the proper shell.  And
while we are at it, we write this wrapper to also deal with TAP tests in
a better way, running them through the prove(1) utility, so that their
results are correctly recognized and reported.

the failed tests in the second run.

'v1.12.1-95-gd5443e4' of 20102-07-01, "parallel-tests: reimplement

Anyway, the use case that has been broken is not realistic (who is
going to run "make recheck" two times in one second, without modifying
any of the tests or the tested programs in the meantime?), so we believe
the best fix is to simply work around the issue in the affected test
