Subject: [PATCH] Run each test in a process-private subdirectory.

* tests/defs.in: Employ a trap to clean up at the end of the
test in case the test succeeded.  This needs to be revisited
because we would like to keep the output of XPASSing tests.
Also, note when we were interrupted by a signal.  Code taken
from Autoconf's _AC_INIT_PREPARE.
If $keep_testdirs is set, keep them even for successful tests.
* tests/Makefile.am (check-clean-local): New target.  Remove all
tests subdirs, but also make them writable first.  The latter
was already needed without per-test subdirs.
(distclean-local): Depend upon check-clean-local.
* tests/Makefile.in: Regenerate.
* tests/.cvsignore, tests/.gitignore: Adjust.

 	Fix default includes ordering to be `-I. -I$(srcdir) ...' again.
 	* automake.in (handle_compile): Put -I$(srcdir) before include
 	paths for config headers, as was done before Automake 1.10, but
