+       tests: fix spurious failure on fast machines
+       * tests/aclocal-acdir.test: Avoid spurious failures due to caching
+       issues, by cleaning the autom4te cache between all the aclocal
+       invocations, and by always calling autoconf with the `--force'
+       flag.

 +
 +      tests: minor optimizations/simplifications in some aclocal tests
 +      * acloca11.test: Instead of running ./configure and then grepping
 +      the file it has produced, directly grep configure.  Add trailing
 +      `:' command.
 +      * acloca12.test: Likewise.
 +      * acloca10.test: Likewise.  Also, remove the autom4te caches
 +      by hand, instead of sleeping to ensure they get outdated and
 +      ignored.
 +      * aclocal9.test: Likewise.
 +      * acloca18.test: Likewise.  Also, do not remove file `foo',
 +      which is not being created anymore.
 +      * acloca20.test: The test makes sense only if the system support
 +      real symlinks, so skip it if this is not the case.  This allows
 +      for various simplifications.

 +
 +      prove: avoid weird signal-related bug
 +      * tests/defs (trap): In the trap code dealing with SIGPIPE
 +      signal, ignore further signals of the same kind.
 +      See also Test::Harness issue [rt.cpan.org #70855], archived at
 +      <https://rt.cpan.org/Ticket/Display.html?id=70855>

 +
 +      tests: allow use of `prove' to run automake testsuite
 +      * tests/prove-runner: New helper script; mostly it wraps
 +      our `*.test' test scripts to make them runnable by the
 +      `prove' utility.
 +      * tests/Makefile.am (EXTRA_DIST): Distribute it.
 +      (PROVE, AM_PROVEFLAGS, AM_PROVECMD): New variables.
 +      (prove, installprove): New targets, used run the automake
 +      testsuite through the `prove' utility.
 +      * tests/gen-testsuite-part: For any considered dependency,
 +      generate a variables that groups all the tests depending on
 +      it.  This is especially useful for use in the new `prove'
 +      and `installprove' targets, which cannot rely on make for
 +      inter-test dependencies, and have to handle them "by hand".
