Make the tests runnable on a read-only src. To do this you must make sure
that you create one of the object directories make knows (see make(1)).
This uses the -C flag, so add a test that checks that make actually accepts
-C. Also fix the test that selects csh via the .SHELL target to work for
tcsh users too.

This commit renames shell_test to shell_test.sh. There is no history
to preserve so go without a repo-copy.

Chmod the shell testscript to be executable if it isn't already. According

do so. Try to be on the safe side.

Switch over to a different, more flexible test output protocol that's
understood by Perl's Test::Harness module and prove(1) commands.

Update README to describe the new protocol. The work's broken down into
two main sets of changes.

First, update the existing test programs (shell scripts and C programs)
to produce output in the ok/not ok format, and to, where possible, also
produce a header describing the number of tests that are expected to be
run.

Second, provide the .t files that actually run the tests. In some cases
these are copies of, or very similar too, scripts that already existed.
I've kept the old scripts around so that it's possible to verify that
behaviour under this new system (in terms of whether or not a test fails)
is identical to the behaviour under the old system.

Add a TODO file.

Add a regression test for the alternate shell specification.

Now that make more correctly handles variable assignments
in .MAKEFLAGS targets enable the regression test for this.

Back out something I'm working on that crept in with the last commit.

Remove extra spaces. Remove double quotes around error messages -
they are not needed and will actually be printed.

The regression-tests for 'make' *expect* to trigger make's warning:
warning: duplicate script for target "double" ignored
The regression-tests do try to hide that message, but the message does
still appear when using -j (eg: 'make -j5 buildworld'). This changes the
regression-test so the expected warning message will not be seen even
when -j is specified.

Add a test for what was fixed in revisions 1.39 and 1.50 of

Moved make(1) regression tests from src/Makefile to where they
belong (src/tools/regression/usr.bin/make), and use the latter
to test if make(1) is adequate for building the world.

Hide the test in <target> under '.if make(<target>)' so as to not get any

As of revision 1.38 of make/parse.c, our make(1) will warn too. Note that
this isn't just for the sake of testing behaviour, and that things really
do break if this regression occurs.

Grrr, make the test for embedded variables in the left-hand-side actually do
