+    * When statement is of the form { ... }, the leading { MUST BE ON

-	gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)

-      there may be other gcc versions that also suffer this fate.

-	readline-4.1-5
-	readline2.2.1-2.2.1-2
-	readline-devel-4.1-5
-
-      One work-a-round is to compile calc WITHOUT readline.  In the
-      Makefile be sure that:
-
-	USE_READLINE=
-	READLINE_LIB=
-	READLINE_INCLUDE=
-
-      i.e., these Makefile vars are empty.
-
-      If you must use readline, then an alternate work-a-round is to
-      change the DEBUG Makefile variable to either:
-
-	compile for speed:  -O3		(or -O2 if you do not have -O3)
-	compile to debug:   -g3		(or -g if you do not have -g3)
-
-      but not both.

-
-      The work-a-round is to compile calc without the optimizer.  If this

-      work-a-round for gcc-2-96.
-
-      There is a work-a-round for this architecture us one is using the
-      Solaris CC on the sparcv9.  It has been reported that setting the
-      following Makefile variables will produce a working version of
-      calc on the sparcv9 under 64 bit Solaris:
-
-	    LCC="cc -xarch=v9"
-	    CCWARN="-DFORCE_STDC -w"
-	    DEBUG="-fast -xarch=v9"
-
-    * Under BSDI v4, the warnings of the form:
-
-	/usr/include/ctype.h:147: warning: `__runetype' defined but not used
-	/usr/include/ctype.h:161: warning: `__isctype' defined but not used
-	/usr/include/ctype.h:170: warning: `toupper' defined but not used
-	/usr/include/ctype.h:177: warning: `tolower' defined but not used
-
-      are seen.	 These warnings are the result of mis-features in BSDI
-      include files.  They do not have an impact on the operation
-      or performance.  The work-a-round is to ignore these warnings
-      under BSDI.
+      This needs to be changed.  See also "help statement", "help unexpected",
+      and "help todo".

+MATH ERROR HANDLING
+-------------------
 
-Your program MUST provide a function called math_error.	 This is called by
-the math routines on an error condition, such as malloc failures or a
-division by zero.  The routine is called in the manner of printf, with a
-format string and optional arguments.  (However, none of the low level math
-routines currently uses formatting, so if you are lazy you can simply use
-the first argument as a simple error string.)  For example, one of the

+an internal computation error.  The routine is called in the manner of

-	math_error("Division by zero");
+	    void math_error(char *fmt, ...);
 
-Your program can handle errors in basically one of two ways.  Firstly, it
-can simply print the error message and then exit.  Secondly, you can make
-use of setjmp and longjmp in your program.  Use setjmp at some appropriate
-level in your program, and use longjmp in the math_error routine to return
-to that level and so recover from the error.  This is what the calc program
-does.
+Your program must handle math errors in one of three ways:
 
-For convenience, the link library libcalc.a contains a math_error routine.
-By default, this routine simply prints a message to stderr and then exits.
-By simply linking in this link library, any calc errors will result in a
-error message on stderr followed by an exit.

+	By default, this routine simply prints a message to stderr and
+	then exits.  By simply linking in this link library, any calc
+	errors will result in a error message on stderr followed by
+	an exit.
 
-	-I${LIBDIR} -L${LIBDIR} -lcalc
+    2) Use setjmp and longjmp in your program
 
-If one sets up calc_jmp_buf, and then sets calc_jmp to non-zero then
-this routine will longjmp back (with the value of calc_jmp) instead.
-In addition, the last calc error message will be found in calc_error;
-this error is not printed to stderr.  The calc error message will
-not have a trailing newline.
+	Use setjmp at some appropriate level in your program, and let
+	the longjmp in math_error() return to that level and to allow you
+	to recover from the error.  This is what the calc program does.
 
-For example:
+	If one sets up calc_matherr_jmpbuf, and then sets
+	calc_use_matherr_jmpbuf to non-zero then math_error() will
+	longjmp back with the return value of calc_use_matherr_jmpbuf.
+	In addition, the last calc error message will be found in
+	calc_err_msg; this error is not printed to stderr.  The calc
+	error message will not have a trailing newline.
 
-    #include <setjmp.h>
+	For example:
 
-    extern jmp_buf calc_jmp_buf;
-    extern int calc_jmp;
-    extern char *calc_error;
-    int error;
+	    #include <setjmp.h>
+	    #include "lib_calc.h"
 
-    ...
+	    int error;
 
-    if ((error = setjmp(calc_jmp_buf)) != 0) {
+	    ...
 
-	    /* reinitialize calc after a longjmp */
-	    reinitialize();
+	    if ((error = setjmp(calc_matherr_jmpbuf)) != 0) {
+
+		    /* report the error */
+		    printf("Ouch: %s\n", calc_err_msg);
+
+		    /* reinitialize calc after the longjmp */
+		    reinitialize();
+	    }
+	    calc_use_matherr_jmpbuf = 1;
+
+	If calc_use_matherr_jmpbuf is non-zero, then the jmp_buf value
+	calc_matherr_jmpbuf must be initialized by the setjmp() function
+	or your program will crash.
+
+    3) Supply your own math_error function:
+
+	    void math_error(char *fmt, ...);
+
+	Your math_error() function may exit or transfer control to outside
+	of the calc library, but it must never return or calc will crash.
+
+External programs can obtain the appropriate calc symbols by compiling with:
+
+	-I${INCDIR} -L${LIBDIR} -lcalc
+
+-------------------------
+PARSE/SCAN ERROR HANDLING
+-------------------------
+
+The scanerror() function is called when calc encounters a parse/scan
+error.  For example, scanerror() is called when calc is given code
+with a syntax error.
+
+The variable, calc_print_scanerr_msg, controls if calc prints to stderr,
+any parse/scan errors.  By default, this variable it set to 1 and so
+parse/scan errors are printed to stderr.  By setting this value to zero,
+parse/scan errors are not printed:
+
+	#include "lib_calc.h"
+
+	/* do not print parse/scan errors to stderr */
+	calc_print_scanerr_msg = 0;
+
+The last calc math error or calc parse/scan error message is kept
+in the NUL terminated buffer:
+
+	char calc_err_msg[MAXERROR+1];
+
+The value of calc_print_scanerr_msg does not change the use
+of the calc_err_msg[] buffer.  Messages are stored in that
+buffer regardless of the calc_print_scanerr_msg value.
+
+The calc_print_scanerr_msg and the calc_err_msg[] buffer are declared
+lib_calc.h include file.  The initialized storage for these variables
+comes from the calc library.  The MAXERROR symbol is also declared in
+the lib_calc.h include file.
+
+Your program must handle parse/scan errors in one of two ways:
+
+    1) exit on error
+
+	If you do not setup the calc_scanerr_jmpbuf, then when calc
+	encounters a parse/scan error, a message will be printed to
+	stderr and calc will exit.
+
+    2) Use setjmp and longjmp in your program
+
+	Use setjmp at some appropriate level in your program, and let
+	the longjmp in scanerror() return to that level and to allow you
+	to recover from the error.  This is what the calc program does.
+
+	If one sets up calc_scanerr_jmpbuf, and then sets
+	calc_use_scanerr_jmpbuf to non-zero then scanerror() will longjmp
+	back with the return with a non-zero code.  In addition, the last
+	calc error message will be found in calc_err_msg[]; this error is
+	not printed to stderr.	The calc error message will not have a
+	trailing newline.
+
+	For example:
+
+	    #include <setjmp.h>
+	    #include "lib_calc.h"
+
+	    int scan_error;
+
+	    ...
+
+	    /* delay the printing of the parse/scan error */
+	    calc_use_scanerr_jmpbuf = 0;	/* this is optional */
+
+	    if ((scan_error = setjmp(calc_scanerr_jmpbuf)) != 0) {
+
+		    /* report the parse/scan */
+		    if (calc_use_scanerr_jmpbuf == 0) {
+			    printf("parse error: %s\n", calc_err_msg);
+	    	    }
+
+		    /* initialize calc after the longjmp */
+		    initialize();
+	    }
+	    calc_use_scanerr_jmpbuf = 1;
+
+	If calc_use_scanerr_jmpbuf is non-zero, then the jmp_buf value
+	calc_scanerr_jmpbuf must be initialized by the setjmp() function
+	or your program will crash.
+
+External programs can obtain the appropriate calc symbols by compiling with:
+
+	-I${INCDIR} -L${LIBDIR} -lcalc
+
+---------------------------
+PARSE/SCAN WARNING HANDLING
+---------------------------
+
+Calc parse/scan warning message are printed to stderr by the warning()
+function.  The routine is called in the manner of printf, with a format
+string and optional arguments:
+
+	void warning(char *fmt, ...);
+
+The variable, calc_print_scanwarn_msg, controls if calc prints to stderr,
+any parse/scan warnings.  By default, this variable it set to 1 and so
+parse/scan warnings are printed to stderr.  By setting this value to zero,
+parse/scan warnings are not printed:
+
+	#include "lib_calc.h"
+
+	/* do not print parse/scan warnings to stderr */
+	calc_print_scanwarn_msg = 0;
+
+The last calc calc parse/scan warning message is kept in the NUL
+terminated buffer:
+
+	char calc_warn_msg[MAXERROR+1];
+
+The value of calc_print_scanwarn_msg does not change the use
+of the calc_warn_msg[] buffer.  Messages are stored in that
+buffer regardless of the calc_print_scanwarn_msg value.
+
+Your program must handle parse/scan warnings in one of two ways:
+
+    1) print the warning to stderr and continue
+
+	The warning() from libcalc prints warning messages to
+	stderr and returns.  The flow of execution is not changed.
+	This is what calc does by default.
+
+    2) Supply your own warning function:
+
+	    void warning(char *fmt, ...);
+
+	Your warning function should simply return when it is finished.
+
+External programs can obtain the appropriate calc symbols by compiling with:
+
+	-I${INCDIR} -L${LIBDIR} -lcalc
 
-	    /* report the error */
-	    printf("Ouch: %s\n", calc_error);
-    }
-    calc_jmp = 1;

-The major porting work was performed by Thomas Jones-Low

-
-    I had previous stated to this group that I have successfully managed
-    to port a version of Calc to Windows, and promised some point to
-    post what was required, so here it is.
-
-    One obvious manner of doing this port is to get the latest version
-    of the Cygwin project (http://sources.redhat.com/cygwin/) with the
-    GCC compiler and Un*x tools for Windows and recompile.
-
-    I built my working version using Calc ... I am using Visual C++
-    version 7.0, which is an older version of the Microsoft development
-    tools. The make file provided with Calc is not compatible with
-    NMAKE, so I used the Visual Studio tools to generate another one
-    (not included). Calc is built in two parts, calc.dll, which is the
-    library, and calcexe.exe which is the command line interface.
-
-He recommends that you generate by hand all of the header files generated

-
-    align32.h args.h calcerr.h conf.h endian_calc.h

-People who maintain calc need to keep in mind the following:

-The following was added to opcodes.h, config.h, zmath.h and value.h:
-
-	#if defined(_WIN32)
-	#ifdef _EXPORTING
-	  #define DLL	__declspec(dllexport)
-	#else
-	  #define DLL	__declspec(dllimport)
-	#endif
-
-	#else /* Windoz free systems */
-
-	  #define DLL
-
-	#endif /* Windoz free systems */
-
-Then DLL was added in front of all the exported functions.  For example:
-
-    extern int configtype(char*);

 that are shipped with calc.  See above for example of how to read in
 and execute these files.

+    mul_loop(repeat,x) defined
+    mul_ratio(len) defined
+    best_mul2() defined
+    sq_loop(repeat,x) defined

+    best_sq2() defined
+    pow_loop(repeat,x,ex) defined
+    pow_ratio(len) defined
+    best_pow2() defined
+
+    These functions search for an optimal value of config("mul2"),
+    config("sq2"), and config("pow2").  The calc default values of these
+    configuration values were set by running this resource file on a
+    1.8GHz AMD 32-bit CPU of ~3406 BogoMIPS.
+
+    The best_mul2() function returns the optimal value of config("mul2").
+    The best_sq2() function returns the optimal value of config("sq2").
+    The best_pow2() function returns the optimal value of config("pow2").
+    The other functions are just support functions.
+
+    By design, best_mul2(), best_sq2(), and best_pow2() take a few
+    minutes to run.  These functions increase the number of times a
+    given computational loop is executed until a minimum amount of CPU
+    time is consumed.  To watch these functions progress, one can set
+    the config("user_debug") value.
+
+    Here is a suggested way to use this resource file:
+
+	; read alg_config
+	; config("user_debug",2),;
+	; best_mul2(); best_sq2(); best_pow2();
+	; best_mul2(); best_sq2(); best_pow2();
+	; best_mul2(); best_sq2(); best_pow2();
+
+    NOTE: It is perfectly normal for the optimal value returned to differ
+    slightly from run to run.  Slight variations due to inaccuracy in
+    CPU timings will cause the best value returned to differ slightly
+    from run to run.
+
+    One can use a calc startup file to change the initial values of
+    config("mul2"), config("sq2"), and config("pow2").  For example one
+    can place into ~/.calcrc these lines:
+
+	config("mul2", 1780),;
+	config("sq2", 3388),;
+	config("pow2", 176),;
+
+    to automatically and silently change these config values.
+    See help/config and CALCRC in help/environment for more information.
