+       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".
