+Other items of note:
+
+    * There is a bug in gcc-2.95 that causes calc, when compiled with -O2,
+      to fail the regression test.  The work-a-round is to compile with -O
+      or to use gcc-2.96 or later.
+
+    * There is a bug in some versions of the Dec/Compaq cc for the Alpha
+      where the following:
+
+	    #include <stdio.h>
+	    #define SVAL(a,b) (unsigned long)(0x ## a ## b ## ULL)
+	    main(){SVAL(b8a8aeb0,8168eadc);}
+
+      fails because it puts a space inside the concatenated hex.  Calc
+      has code that is affected by this bug.  This bug has been reported
+      to Compaq and may be fixed in the future.  A work-a-round is to
+      compile with cc -std0 or to use a later version of their compiler.
+
+    * On a Digital UNIX V4.0F (Rev. 1229) on a 500 Mhz 21264, make check
+      dies a horrible death starting in test 600 and 622 gives 100s of
+      messages for calc version 2.11.0t9.4 using the Dec's cc with -O2:

+	600: Beginning test_bignums

+	**** t6 != a6: 622: algcheck 1
+	**** t4 != a4: 622: algcheck 1
+	...
+
+	it finally hangs at test 2000.
+
+      The work-a-round is to compile calc without the optimizer.  If this
+      happens to you, try compiling without -O and without -O2.  I.e., in
+      the Makefile, set:
+
+	DEBUG= -g

+Following is the change from calc version 2.11.0t8.9.1 to date:
+
+    The config("verbose_quit") will control the printing of the message:
+
+	    Quit or abort executed
+
+	when a non-interactive ABORT, QUIT or EXIT is encounted.  By default,
+	config("verbose_quit") is TRUE and the message is printed.  If one does:
+
+	    config("verbose_quit", 0)
+
+	the message is disabled.
+
+    Added 8400 regression test set and test8400.cal to test the new
+    quit and config("verbose_quit") functionality.
+
+    Fixed the BigEndian BASEB==16 regression bugs by correctly swapping
+    16 bit HALFs in a 64 bit value (such as a 64 bit file pointer).
+
+    Added calclevel() builtin to calculation level at which it is called.
+
+    Added help/calclevel and help/inputlevel help files.
+
+    Removed regression tests 951 and 5984 so that the regress test will
+    run in non-interactively / without a TTY such as under Debian's
+    build daemon.
+
+    The eval(str) builtin will return an error-value rather than cause
+    an execution error str has a scan-error.
+
+    Declarations are permitted to end with EOF as well as a newline or ';'.
+
+    When prompt() occurs while reading a file, it will take input from
+    the terminal rather than taking it from a file.  For example:
+
+	    /* This demonstrates the use of prompt() and some other things  */
+	    config("verbose_quit", 0);
+	    define getnumber() {
+		local x;
+		for (;;) {
+		    x = eval(prompt(">>> "));
+		    if (isnum(x))
+			return x;
+		    print "Not a number! Try again";
+		}
+	    }
+	    print "This will display the sqrt of each number you enter";
+	    print "Enter quit to stop";
+	    for (;;) {
+		print sqrt(getnumber());
+	    }
+	    print "Good bye";
+
+	Comments entered at input terminal level may be spread over several
+	lines.  For example:
+
+	    /*
+	     * Assume that this calc script is called: comment.cal
+	     * Then these commands now work:
+	     *	cat comment.cal | calc
+	     *	calc < comment.cal
+	     */
+	    print "Hello";
+
+    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 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.
+
+    Added the piforever() funcion to lib/pi.cal.  It was written by
+    Klaus Alexander Seistrup <klaus@seistrup.dk> and was inspired by
+    an algorithm conceived by Lambert Meertens.  (See also the ABC
+    Programmer's Handbook, by Geurts, Meertens & Pemberton, published
+    by Prentice-Hall (UK) Ltd., 1990.)  The piforever() funcion prints
+    digits of pi for as long as your memory and system uptime allows.  :-)
+
+    Fixed the URLs found thruout the source and documentation which did
+    not and in /, but should for performance and server load reasons.
+
+    Cleaned up and improved handling of "mat" and "obj".  The comma in:
+
+	    mat A[2], B[3];
+
+	is changed to whatever is appropriate in the context:
+
+	    + comma operator
+	    + separator of arguments in a function call
+	    + separator of arguments in a defintion
+	    etc.
+
+	The expression (mat A[2]), B[3] returns B[3], assuming B already
+	exists as something created by a statement like: global mat B[4].
+
+	What used to be done by the expression:
+
+	    mat A[2], B[3]
+
+	will now require something like:
+
+	    mat A[2], mat B[3]	or 	A = mat[2], B = mat[3]
+
+	For example, if obj point and obj pair are known types, the
+	following is now allowed:
+
+	    L = list(mat[2], mat[3], obj point, obj pair)
+
+	As another example, the following is allowed:
+
+	    define f(a = mat[2] = {3,4}) = 5 * a;
+
+	as well as the following:
+
+	    obj point {x,y}, PP = obj pair {A,B} = {obj point, obj point}
+
+	which creates two object types at compile time and when executed,
+	assigns a pair-object value to a variable PP.
+
+    Fixed a bug whereby a for loop would behave incorrectly.  For example:
+
+	    config("trace", 2),
+	    global x;
+	    define f() {for ( ; x > 0; x--) {print x;}}
+	    x = 5, f()
+
+	will stop after printing 1 instead of looping forever.
+
+    Added values l_format, which when CHECK_L_FORMAT is defined ahead
+    of including longlong.h will help detect when a system can deal with
+    'long long' but not '%lld' in printf.  If a system with 'long long'
+    uses '%ld' to print a 64 bit value, then l_format will be > 0;
+    othewise if "%lld" is required, l_format will be < 0.
+
+    Added HAVE_STRDUP Makefile variable as well as the have_strdup.c
+    program that forms the have_strdup.h file.  The have_strdup.h file
+    will define HAVE_STRDUP is the system has strdup().  If HAVE_STRDUP
+    is not defined, then calc will use calc_strdup() to simulate
+    the real strdup() function.
+
+    Calc no longer makes use of sys_errlist and sys_nerr.  Some systems
+    no longer suppor these values (even though they should from a
+    legacy prospective).  Calc now relies on the fact that strerror()
+    will return NULL of no such system error exists.  System errors >=
+    10000 will be considered calc errors instead.  The Makefile symbol
+    ERRNO_DECL has gone away as well as calc_errno.c and calc_errno.h.
+
+    On system errors are are not known to to the libc strerror() function,
+    strerror() will now print something such as:
+
+	    Unknown error 9999

- * errno - Determine how to declare errno, sys_errlist and sys_nerr
- *
- * On most machines: errno sys_errlist and sys_nerr are declared
- * by either <stdio.h> and/or <errno.h>.  But some systems declare
- * them somewhere else or do not declare them at all!
- *
- * If the system were doing a proper job in headers, this should declare them:
- *
- *	#include <stdio.h>
- *	#include <errno.h>
- *
- * But one some systems one must explicitly declare them as:
- *
- *	extern int errno;
- *	extern const char *const sys_errlist[];
- *	extern int sys_nerr;
- *
- * and on some old systems they must be explicitly and incorrectly declared as:
- *
- *	extern int errno;
- *	extern char *sys_errlist[];
- *	extern int sys_nerr;
- *
- * The purpose of this utility is try and find the right way to declare
- * them and to output the middle of a header file called calc_errno.h.

+
+SYNOPSIS
+    calclevel()
+
+TYPES
+    return	nonnegative integer
+
+DESCRIPTION
+    This function returns the calculation level at which it is called.
+    When a command is being read from a terminal or from a file,
+    calc is at calculation level zero.  The level is increased
+    by 1 each time calculation starts of a user-defined function
+    or of eval(S) for some expression S which evaluates to a string.  It
+    decreases to zero if an error occurs or a quit or abort statement
+    is executed.  Otherwise, it decreases by 1 when the calculation
+    is completed.  Except when an error occurs or abort is executed,
+    the input level is not affected by changes in the calculation level.
+
+    Zero calculation level is also called top calculation level; greater
+    values of calclevel() indicate calculation is occurring at greater
+    depths.

+DESCRIPTION
+    This function returns the input level at which it is called.
+    When calc starts, it is at level zero.  The level is increased
+    by 1 each time execution starts of a read file command or a call to
+    eval(S) for some expression S which evaluates to a string.  It
+    decreases by 1 when a file being read reaches EOF or a string
+    being eval-ed reaches '\0', or earlier if a quit statement is
+    encountered at top calculation-level in the flle or string.  It
+    decreases to zero if an abort statement is encountered at any
+    function-level in the file or string.  If a quit or abort
+    statement is encountered at top calculation-level at top input-level,
+    calc is exited.
+
+    Zero input level is also called top input level; greater values
+    of inputlevel() indicate reading at greater depths.
