+template for CONFIG.H case sensitive rules can be enabled with defining
+WANT_CASE_SENSITIVE_TARGETS. For recent version of VMS there is a case
+sensitive file system: ODS5. To make use of that, additionally un-defining

+versions of make need to be built to have any case sensitivity for VMS

-This package has a number of problems which preclude me from
-distributing it with make as a default "make check" test suite. The
-most serious of these is that it's not parallelizable: it scribbles all
-over its installation directory and so can only test one make at a
-time. I simply don't have time to do more with this than I am so far;
-I'm very actively interested in finding someone willing to overhaul the
-test suite infrastructure. If you're interested, contact me (see below)!
-
-The test suite thus far has been written by Steve McGee, Chris Arthur,
-and Paul D. Smith. It is covered by the GNU General Public License

-
-The test suite requires Perl and is known to work with Perl 4.036 and
-Perl 5.004 (available from ftp.gnu.org, and portable to many machines).
-Earlier or later versions may work; I don't know. It assumes that the

+The test suite was originally written by Steve McGee and Chris Arthur.
+It is covered by the GNU General Public License (Version 2), described
+in the file COPYING. It has been maintained as part of GNU make proper
+since GNU make 3.78.
+
+The test suite has a number of problems which should be addressed. One
+VERY serious one is that there is no real documentation. You just have
+to see the existing tests. Use the newer tests: many of the tests
+haven't been updated to use the latest/greatest test methods. See the
+ChangeLog in the tests directory for pointers.
+
+The second serious problem is that it's not parallelizable: it scribbles
+all over its installation directory and so can only test one make at a
+time. The third serious problem is that it's not relocatable: the only
+way it works when you build out of the source tree is to create
+symlinks, which doesn't work on every system and is bogus to boot. The
+fourth serious problem is that it doesn't create its own sandbox when
+running tests, so that if a test forgets to clean up after itself that
+can impact future tests.
+
+The test suite requires Perl. These days, you should have at least Perl
+5.004 (available from ftp.gnu.org, and portable to many machines). It
+used to work with Perl 4.036 but official support for Perl 4.x was
+abandoned a long time ago, due to lack of testbeds, as well as interest.
+
+The test suite assumes that the first "diff" it finds on your PATH is
+GNU diff, but that only matters if a test fails.
To run the test suite on a UNIX system, use "perl ./run_make_tests"
