+Following is a repost of the public domain 'make' that I posted
+to net.sources a couple of months ago.  I have fixed a few bugs, and
+added some more features, and the resulting changes amounted to
+about as much text as the whole program (hence the repost).
+
+For those that missed the net.sources posting, this is a public domain
+re-implementation of the UNIX make program.  There is no manual included;
+for documentation, refer to a UNIX manual, or the source.
+
+Here is a list of the changes made:
+
+i)	If '-' (ignore) or '@' (silent) where used at the start
+	of a command, their effect was not turned off for the following
+	commands.
+ii)	A special target (.SUFFIXES, .PRECIOUS) or a rule (.c.o, .a.o),
+	if first in the file would be taken as the default target.
+	This resulted in error messages like "Don't know how to
+	make .c", because things like .SUFFIXES were being made.
+	This was further complicated by ---
+iii)	Special target lines with no dependents (ie. .SUFFIXES:\n)
+	were not clearing out the existing dependents like
+	they should.
+iv)	Default rules could not be redefined because of the error
+	checking for commands being defined twice.  Now you are
+	allowed to define a target beinging with '.', having
+	no dependents with commands.
+v)	The -q option didn't do the time comparison correctly,
+	or clear the variable used to keep track of this.  Thus
+	it didn't work very well.
+vi)	The syntax ${..} for macro's supported by UNIX make was
+	not supported.
+vii)	There wuz a couple of spelling errors.
+viii)	When make checked for implicit rules on targets without
+	a suffix, there were problems.  (Note: The ~ feature of
+	UNIX make wasn't and still isn't supported)
+ix)	The -n option did not print @ lines like it was supposed to.
+x)	:: added.  (See UNIX manual)
+xi)	$? added.  (see UNIX manual)
+
+Hacked further by Ceriel Jacobs to make it work better. Use this "make" to
+install ACK under Microsoft Xenix V3.2. Some of the makefiles are just too
+big for the Xenix "make". Strange, they work on a PDP-11 ...
