gnulib tests.
* gl/modules/rename-tests.diff (Makefile.am): New file, to add
LIBINTL to LDADD, since we avoid canonicalize-lgpl module.

(build_collating_symbol, parse_bracket_element, build_equiv_class)
(free_tree): Mark unused parameters.
* gl/lib/regex_internal.h.diff (re_string_elem_size_at): New file,
to mark unused parameters.
* gl/lib/printf-args.c.diff (PRINTF_FETCHARGS): New file, to avoid
type mismatch.
* gl/lib/vasnprintf.c (VASNPRINTF): New file, to avoid shadowing
local variable name.
* .gitignore: Ignore temporary build artifacts.
* gnulib-tests/Makefile.am (AM_CFLAGS): Add WARN_CFLAGS.
* configure.ac (enable-gcc-warnings): Also use -funit-at-a-time,
to silence gcc 4.3.4 -Wdisabled-optimization.
* .gitignore: Ignore some more files.
* build-aux/check.mk: Remove, not needed any more.
* tests/Makefile.am (AUTOMAKE_OPTIONS): Add parallel-tests and
color-tests.
* tests/check.mk: Do not include build-aux/check.mk any more.
(SUFFIXES, TEST_LOGS): Remove.
(TESTS_ENVIRONMENT): Use $$f rather than $$tst in $PERL invocation.
* gnulib-tests/Makefile.am: Do not include build-aux/check.mk.
(AUTOMAKE_OPTIONS): New macro, add parallel-test and color-tests.
(TEST_LOGS): Remove.
* tests/Makefile.am: Define AUTOMAKE_OPTIONS, so check.mk can append.
* tests/check.mk: Define SUFFIXES, so check.mk can append.
* build-aux/check.mk (SUFFIXES): Append, so as not to evoke
automake warning the prior definition in gnulib-tests/gnulib.mk.
(AUTOMAKE_OPTIONS): Likewise.
* gnulib-tests/Makefile.am (TEST_LOGS): Define.
Include build-aux/check.mk

* m4/jm-macros.m4 (coreutils_MACROS) [ARGMATCH_DIE_DECL]: Omit the
"extern " prefix to "void usage ()", so that the macro string value can
be used to construct a function definition in gnulib's test-argmatch.c.
