Regression Tests
----------------
GNU Make contains a suite of regression tests. To run them use "make check"
after building GNU Make. If they fail a tar package will be created
containing useful information, which can be emailed (as an attachment) to
the <bug-make@gnu.org> mailing list.
Please note that since these tests rely on known-good-output comparisons,
they can show spurious failures on some systems (particularly non-POSIX systems
such as Windows).
