+    Added:
+
+	-D calc_debug[:lib_debug:[user_debug]]
+
+    to set the initial value of config("calc_debug"), config("lib_debug")
+    and config("user_debug").
+
+    The : separated strings of -D are interpreted as signed 32 bit values.
+    After an optional leading sign a leading zero indicates octal
+    conversion, and a leading ``0x'' or ``0X'' hexadecimal conversion.
+    Otherwise, decimal conversion is assumed.
+
+    Reordered the config structure moving calc_debug ahead of lib_debug.
+
+    Added bits 4 and 5 to config("calc_debug"):
+
+	4	Report on changes to the state of stdin as well as changes
+		to internal variables that control the setting and restoring
+		of stdin.
+
+	5	Report on changes to the run state of calc.
+
+    Fixed portability issue in seed.c relating to /dev/urandom and ustat.
+
+    Added a fix from Martin Buck <mb@netwings.ch> to detect when
+    calc aborts early instead of completing the regression test.
+    Now 'make chk' will require the last line of calc output to
+    end in the string ``Ending regression tests''.
+
+    Added a patch from Martin Buck <mb@netwings.ch> to allow use of
+    GNU-readline.  Note that GNU-readline is not shipped with calc.
+    His patch only provides the hooks to use it.  One must comment out:
+
+	USE_READLINE=
+	READLINE_LIB=
+	READLINE_INCLUDE=
+
+    and comment in:
+
+	USE_READLINE= -DUSE_READLINE
+	READLINE_LIB= -lreadline -lhistory
+	READLINE_INCLUDE= -I/usr/include/readline
+
+    in addition to pre-installing GNU-readline in your system to use
+    this facility.
+
+    Changed the "object already defined" math_error message to a
+    scanerror message.
+
+    Removed the limit on the number of object types.
+
+    Calc tarballs are now named calc-version.tar.gz and untar into
+    a sub-directory called calc-version.
+
+    Made a small change to declarations of static variables to reduce
+    the internal opcodes needed to declare them.
+
+    Fixed a permission problem on ranlib-ed *.a files that was reported
+    by Michael Somos <somos@grail.cba.csuohio.edu>.
+
+    Added patch by Klaus Alexander Seistrup <klaus@seistrup.dk> related
+    to GNU-readline:
+
+	+ enable calc specific bindings in ~/.inputrc
+	+ save a copy of your session to disk and reload them next
+	  time you're using calc
+	+ only add a line to the history if it is different from
+	  the previous line
+
+    Added the Makefile symbol HAVE_GETRUSAGE to determine if the
+    system supports the getrusage() system call.
+
+    Fixed the make depend code in the custom and sample Makefiles.
+
+    Fixed how the help/builtin file is formed.  The help/Makefile is
+    now given the name of the native C compiler by the top level Makefile.
+
+    The include files are installed under INCDIRCALC (a new Makefile variable)
+    which by default is ${INCDIR}/calc.  The INCDIR (also a new Makefile var)
+    by default is /usr/local/include.  Include files previously installed
+    directly under ${LIBDIR} will be removed.
