tests defs: one more environment sanitization (corner case)

* tests/defs (am__using_gmake): Initialize.  The `using_gmake'
subroutine was using this variable for caching, but wasn't
initializing it, which could cause problems in the (admittedly
very unlikely) case in which it was pre-existent in the
environment.

Merge branch 'master' into testsuite-work

Merge branch 'tests-man-fixes'

tests: add forgotten test scripts to $(TESTS)

* tests/Makefile.am (TESTS): Added test scripts  man[678].test,
which have been present on the filesystem and in the repository,
but which had erroneously been left out from $(TESTS).

Merge branch 'check-tests-list' into testsuite-work

maintcheck: consistency of list of test scripts

* CheckListOfTests.am: New file.
(maintainer-check-list-of-tests): New target,
check for consistency between list of tests defined in the
including Makefile and list of tests on the filesystem.
(clean-maintcheck-testslist-tmp): New rule, to clean up the
temporary files that might be left around by the rules associated
with the previous target.
(clean-local): Depend on it.
* lib/Automake/tests/Makefile.am: Include `CheckListOfTests.am'.
(maintainer-check): Added dependency from the new target
`maintainer-check-list-of-tests'.
* tests/Makefile.am: Likewise.
* Makefile.am (maintainer-check-list-of-test): New target,
calling recursively into `tests/' and `lib/Automake/tests/',
using ...
(TEST_SUBDIRS): ... this new variable.

tests: ensure verbose printing of captured make output

make output.

Also, do not reject slow dependency extractors (which we might
be forced to use now that $CC is not necessarily gcc anymore).
* tests/cond16.test ($required): Remove 'gcc', as any working
C compiler should be enough.
Since we are at it, throw in few minor tweakings (mostly cosmetic,
stylistic, or consistency-related).

test defs: increase coverage w.r.t. GNU make

* tests/defs (GNUmake): Instead of just skipping the tests
requiring GNU make if $MAKE is not GNU make, try to look for
it and, if found, redefine $MAKE accordingly.  This will help
to transparently increase coverage on non-GNU systems which
have GNU make available in PATH.

tests: improve few inter-tests references

* tests/acloca22.test: Improve and extend the heading comments.
Add reference to related tests 'remake-deleted-m4-file.test' and
'remake-renamed-m4-macro-and-file.test'.  Since we are at it,
add trailing `:' command, and few blank lines for readability.
* tests/remake-renamed-m4-macro-and-file.test: In the heading
comments, add reference to the related test 'acloca22.test'.

Merge branch 'master' into testsuite-work

tests: few more checks on automatic remake support

* tests/remake-all-1.test: New test, check that the "all" target
triggers rebuilt of outdated Makefiles.
* tests/remake-all-2.test: Likewise, but for when the makefiles
are not named `Makefile'.
* tests/Makefile.am (TESTS): Update.

tests: check some remake features with non-GNU make too

* tests/acloca14.test ($required): Drop "GNUmake".  This test
works as-is with non-GNU make implementations.
* tests/remake1a.test: Likewise.
* tests/aclocal4.test ($required): Drop "GNUmake".
Modify the test to have it work also with non-GNU make.

* tests/remake10b.test: Likewise.
* tests/remake10c.test: Likewise.
* tests/remake12.test: ($required): Drop "GNUmake".
Adapt the test to make it work also with non-GNU make (if
it supports an "include" directive).

tests: fix spurious failure in 'color2.test'

* tests/color2.test: If $MAKE contains command-line arguments (as
in e.g., "make -j2"), expect's directive "spawn $env(MAKE)" fails
spuriously, because it tries to run "$MAKE" as a single command.
Fix this with proper uses of the TCL `eval' builtin.

tests: extend tests on dependency tracking with VPATH

* tests/depmod-tests.sh: New script, fulfilling a threefold role:
1. it is called to generate a Makefile.am snippet, containing the
   definition of proper lists of tests;
2. it is called to set up a directory containing some common data
   files and autotools-generated files used by the aforementioned
   tests (this is done for speed reasons only); and
3. it is called to properly run those tests, one at a time.
* tests/depcomp9.test: Delete, it's obsolete now.
* tests/depcomp10.test: Likewise.
* tests/Makefile.am ($(srcdir)/depmod-tests.am): Include this
snippet, which defines ...
(depmode_tests): ... this new macro, containing the list of the
newly generated `*.depmod' tests.
(TESTS_EXTENSIONS): Add `.depmod'.
(DEPMOD_LOG_COMPILER): Define.  It calls `depmod-tests.sh', so that
the "depmode tests" will be executed by passing that driver script
a proper parameter.
($(depmod_tests)): New dependency declaration (dummy, but required
in order to have make actually produce expected log files from the
`.depmod.log' suffix rule).
(TESTS): Add $(depmod_tests).
(EXTRA_DIST): Distribute depmod-tests.sh.
Other minor cosmetic changes and reorderings.
* bootstrap: Generate depmod-tests.am.
* tests/.gitignore: Updated.

tests: avoid extra test generation (for `instspc' tests)

We don't really need to generate tons and tons of wrapper test
scripts (presently, ~ 90) just to run what is basically a single
test (specifically, `instspc-tests.sh') with different parameters.
In fact, the possibility of running a single driver script with
multiple files/configurations/parameters is one of the major
selling points of the 'parallel-tests' testsuite driver of
automake.  So why not use ourselves more extensively the best
features we provide?

* tests/instspc-tests.sh: Update heading comments.  Expect
to be executed, not sourced.  Update handling of command-line
arguments.  Adjust to reflect the renaming of "instspc tests"
from `instspc-*.test' to `*.instspc'.
* tests/instspc-data.test: Update heading comments.  Execute
driver script `instspc-tests.sh', instead of sourcing it.
Give more informative messages in case of internal errors.
* tests/Makefile.am (TESTS_EXTENSIONS): Define explicitly (to
`.test' and `.instspc').
(TESTS): Add `$(instspc_tests)'.
(generated_tests): Remove `$(instspc_tests)'.
(INSTSPC_LOG_COMPILER): Define.  Calls `instspc-tests.sh', so
that the "instspc tests" will be now executed by passing that
driver script a proper parameter.
($(instspc_tests)): Remove, we don't need anymore to generate
this tests.
($(instspc_tests:.test=.log)): Remove, substituted by ...
($(instspc_tests:.instspc=.log)): ... this.
($(instspc_tests)): New dependency declaration (dummy, but
required in order to have make actually produce expected log
files from the `.instspc.log' suffix rule).
(MAINTAINERCLEANFILES, generated_tests): Don't extend with
$(instspc_tests) anymore.
Update comments.

build: improve the definition of the list of testcases

* tests/Makefile.am (handwritten_tests): New variable.
(generated_tests): Likewise.
(TESTS): Redefine as the union of the above.
(EXTRA_DIST): Extend using $(handwritten_tests) and
$(generated_tests) rather than $(TESTS).
* tests/gen-parallel-tests: Update accordingly, and
make more robust.

tests skips: shorter and clearer messages

* tests/defs: Use shorter messages when giving reasons for test
skipping; it turns out these shorter messages are also clearer.
If more info might be useful, send them to the log file only.

Merge branch 'master' into testsuite-work

tests: fix self check spurious failure with older bash versions

* tests/self-check-cleanup.test: Add trailing `:' to the test code
passed to $SHELL, otherwise older versions of bash (at least 2.05
and 3.2.39) fail to correctly remove the temporary directory in
the exit trap.

tests: add sanity check to 'self-check-cleanup.test'

* tests/self-check-cleanup.test: Check that the "hacked" file
`defs-static' used by the test differs from the "vanilla" one
in builddir.  This also offers a little more debugging output.

testsuite: display reasons for skips to the console

* tests/Makefile.am (AM_TESTS_ENVIRONMENT): Open file descriptor
`9' to the original stderr; define `stderr_fileno_' to `9', and
export it.
* tests/self-check-report.test: Prevent new spurious failures by
removing from the environment any definition of `stderr_fileno_'.

testsuite: use `skip_' for skipping of tests

give sometimes more detailed messages about the reasons for the
skipping.

The AM_TESTS_SETUP naming was not a good one after all.  It may

latter is a better one simply because it is easier to remember,
and even if you've never heard of it and only know the semantics

test defs: fix 'javac' requirement for older JDK versions

The Java compiler from JDK 1.5 (and presumably earlier versions)
cannot handle the `-version' option by itself; and while it does
print the version number, it then errors out with an usage error:
  $ javac -version
  javac 1.5.0_22
  javac: no source files
  Usage: javac <options> <source files>
  ...
Luckily, adding the `-help' option to the `javac' invocation
seems to fix this problem.

* tests/defs.in (javac): Pass also the `-help' option to the
`javac' program.  Add a comment explaining why it is needed.
